Police seek robbers who shot cop in face

EAST PALO ALTO -- Three SWAT teams swarmed an East Palo Alto neighborhood early Saturday morning hunting for two of three men wanted after a Mountain View police officer was shot in the face Friday night.

The officer was shot as he pursued the three men on a wild car chase up Central Avenue after they robbed a Carl's Jr. and the Bay Food Mart at 209 and 235 East Middlefield Road in Mountain View. Despite his wound, the officer continued to pursue the robbers.

The officer's gunshot wound was not thought to be life-threatening and he was being treated at Stanford Medical Center, police said.

The name of the wounded officer was not released Friday.

The three men, identified as white by police, continued firing at police as they drove through Mountain View and caused an accident at San Antonio and Middlefield roads.

The officer's car died during the chase on Central Avenue after bullets hit it.

The gunmen fled onto Highway 101 and exited at University Avenue in East Palo Alto. They crashed the Isuzu Rodeo they were driving at University Avenue and Donahoe Street.

The man in custody Friday night called police on a cell phone and said he wanted to surrender.

Authorities said it was unclear whether the armed men were wanted in connection with a spree of bank robberies over the past month and a Brinks heist in San Mateo Friday morning.

One of the gunmen was wearing a ski mask, police said.

Mountain View police called the California Highway Patrol for help at 9:56 p.m. Friday after the shooting.

Man Arrested as Search Continues for Man Overboard Sunday, 27-Oct-2002 10:40AM

The San Francisco Police has arrested a man on suspicion of murder this morning after he fought, and then threw, a man over the railing of a "booze cruise'' ship and into the dark waters off Hunter's Point.

The chances of the swimmer's survival are getting slimmer as a U.S. Coast Guard ship continues to search nearly eight hours after responding to the initial report of a man overboard at 11:30 p.m. Saturday.

The Coast Guard has said the man can survive for nearly nine hours in the 57-degree-Fahrenheit waters, an estimate that takes into account the fact that the 30-year-old victim had a few drinks, was not wearing a life jacket, but does know how to swim.

It does not, however, take into account that the man may have been injured during the fight, according to Coast Guard Petty Officer Carl Hausner.

A Coast Guard helicopter, which arrived on the scene at midnight, stopped searching at 4 a.m. but will return at first light, said Hausner. The original boat on the scene, a 41-foot utility boat, has meanwhile been replaced by the Tern, an 87-foot Coast Guard cutter.

"Hopefully this guy made it,'' said police Inspector Sergio Chin, who is leading the investigation. He also had the difficult job of escorting the victim's sobbing girlfriend off the boat and into a waiting patrol car.

Chin is releasing little information but has already interviewed the suspect, a 27-year-old man who eyewitnesses say is bald, around six feet tall and wearing a gray jacket and blue jeans. "He looked very agro,'' meaning aggressive, said one observer.

The police found several witnesses to the fight after meticulously interviewing and writing down contact information for all 270 people aboard the Royal Princess, a cruise ship that departed from Pier 43-1/2 at the Fisherman's Wharf earlier that night.

"Witnesses say the suspect threw the victim overboard,'' confirmed Chin, who would not say how the fight started or whether the victim was already injured when he hit the water.

Chin did say, however, that no one saw the victim after he was thrown overboard, even though the captain of the Royal Princess circled the area several times.

The fight happened during an alleged "booze cruise,'' a nighttime boat tour that attracts young partygoers with easy-access bars and multiple dance floors. No one was available for comment at the Red and White Fleet, the family-owned business that owns the Royal Princess and has been running ferries and tourist boats in the Bay since 1892.

The Coast Guard says it will search until at least noon today and that its search area is expanding with time and moving south along with the currents.

The man may be difficult to spot in the water because he was wearing jeans and a gray shirt, according to the Coast Guard's Hausner. "It's very difficult to spot a person at night with dark clothes.''

High-Speed Police Pursuit Ends in Drainage Ditch

The California Highway Patrol reports that a man was sent to the hospital this morning after leading police in a 100-mph-plus pursuit that ended in a drainage ditch near the Antioch Bridge. Police first attempted to pull over the four-door Honda at 1:07 a.m. today after it sped through a stop sign in Pittsburg, police say. Police chased the car as it roared down state Highway 4 at speeds over 100 mph and eventually headed across the San Joaquin River on the Antioch Bridge. Shortly after reaching the other side of the bridge, however, the car crashed through a fence and overturned in a drainage ditch near the Sherman Island Road exit, police say. The driver apparently tried to flee but ended up flailing around in the murky waters of a drainage ditch until police pulled him out, dried him off and sent him to the hospital for unspecified injuries. Police were unable to confirm reports that the vehicle was stolen. RossWehner0421a09/23/02

Police Release Dispatch Tape from Deadly Crash

Officer Jon Cook died in a car accident last week.

Police have just released the haunting sounds on tape of the panic following last week's fatal crash between two San Francisco police cruisers.

"We've got officers down! We've got officers down! 17th and Dolores," an officer says frantically. "We've just been in a major 7-19."

Two squad cars were chasing after a domestic assault suspect when they collided at the intersection of 17th St. and Dolores in San Francisco. Officer Jon Cook, 38, died in the accident. Three other officers were injured.

Prosecutors have not ruled out charging the assault suspect, Monte Haney, with Cook's death.

Excerpts of 911 Log on Sept. 11 Reveal Unfolding Terror The Associated Press Published: Oct 1, 2001

NEW YORK (AP) - The 911 entries started at 8:47 a.m. with the words "BLDG EXPLOSION." Incident No. 0727 quickly unfolded as a diary of terror, as call after desperate call rolled in from the World Trade Center. Excerpts from the log of the dispatcher for the Fire Department's Emergency Management Service were published Sunday in the Daily News.

The entries were published much as they appeared when they flashed on the computer screen Sept. 11. The time of each call is noted, and messages are abbreviated. MC stands for male caller, FC for female caller, STS for "states."


Then the calls began pouring in from One World Trade Center.




A report from the police aviation unit came in, saying people were falling from the building.

The dimensions of the disaster suddenly grew.









Suddenly all calls from that building ended. Calls from the north tower continued.


The calls ended at 10:33 a.m. as abruptly as they had begun, with a horrifying final note: "ENTIRE TOWER DOWN."

Man kills grandson then self March 31, 2002 --

The Windsor Police Department said a 71-year-old man allegedly shot and killed his teenage grandson today before apparently turning the gun on himself following a four-hour standoff at a mobile home park. Carl Donahoe of Windsor killed himself just before 4 p.m., said Windsor Police Chief David Sederholm.

Sonoma County Sheriff's Department Lt. Matt McCaffrey said Donahoe called a county dispatcher at about 11:57 a.m. to report that he had shot and killed his grandson and that he was planning on taking his own life.

Neighbors said Donahoe lived in the double-wide mobile home with his wife, Pat, and their 18-year-old grandson, Jesse. Pat Donahoe was reportedly playing bingo in Hopland in Mendocino County when the shooting occurred, McCaffrey said.

Law enforcement officers responded to the scene at the Royal Mobile Manor mobile home park at 6555 Old Redwood Highway, and took up positions around the mobile home while making intermittent contact with Donahoe. Meanwhile, residents of the neighborhood were forced to evacuate.

Chief Sederholm said authorities last spoke with Donahoe at about 3:40 p.m. and that he was clearly distraught. Donahoe asked for more time so that he could calm down, Sederholm said, and told authorities to call him back in about 10 minutes.

Just minutes before 4 p.m., however, authorities heard a single gunshot, Sederholm said. A Special Weapons and Tactics team that had taken up positions around the home lobbed two flash-bang diversionary devices inside the mobile home and rushed in through the main entrance.

The home then caught fire and firefighters responded to the scene to douse the blaze.

Sederholm said that Donahoe killed himself. Both his body and the corpse of his grandson remain in the burned mobile home.

The motive for the shooting remains under investigation.

Neighbor Charlotte Duffy described the older man as "really friendly, friendly as he could be."

"He's just as nice as pie," she said.

Duffy said that when she heard a single gunshot around noon, she thought it was a firecracker.

Neighbor Sean Barry, 19, said that both grandfather and grandson worked at Wal-Mart until Jesse quit a couple of months ago. He said Donahoe worked as a door greeter at the store and that Jesse used to work as a stockperson and cart collector.

McCaffrey said the Sheriff's Department has never been called to the suspect's home in past.

100-Mile Chase To Catch Stolen Car Email story to a friend (Livermore-AP) -- Highway patrol officers got a scenic tour of the San Francisco Bay area last night before finally arresting a man suspected in the theft of an SUV. San Jose police say the 100-mile chase began when a stakeout team watching two stolen cars parked at a motel moved in. One man was captured immediately. A second man jumped into a new Ford Explorer and took off.

Police officers began chasing the vehicle -- then turned the chase over to the CHP when the car headed north on Highway 101. The driver crossed the Bay Bridge and headed east on Interstate 580. He finally was stopped just past Livermore.

Jesse Watson of Morgan Hill was booked early today for investigation of evading arrest and possession of a stolen vehicle.

Pair Wanted for Murder Caught After S.F. Chase Gunfire-filled pursuitduring evening rush

A stripper and her boyfriend suspected in killings in two states werecaptured in San Francisco yesterday after trading gunfire with police ina rush-hour chase across the city.

`'They were all over the place. It was a Wild West shootout with thecops,'' said police Inspector Sherman Ackerson.

The 15-minute chase ended on the Embarcadero just north of Pacific BellPark, with 22-year-old Joshua Maxwell and 21-year-old Tessie McFarland,both of Indianapolis, surrounded by more than 20 officers. McFarland wasshot in the neck during the chase and was reported to be in stable conditionlast night at San Francisco General Hospital.

The two were trapped after running red lights, driving the wrong wayup streets and shooting at police, who shot back. In all, dozens of roundswere were fired as the pair weaved through crowded streets in a stolenpickup truck.

``I saw a bullet hit the cop's windshield,'' said witness Lovick Bouphaphah,19, adding that the fleeing driver narrowly missed bystanders as he fledthe police cruisers. ``They were running red lights, and they almost hitabout five cars.''


The driver of the truck, he said, appeared to be enjoying himself. ``Hewas smiling. He looked like he wasn't concerned at all that the cops werechasing him.''

No bystanders were hurt. Officer Jesus Pena was hit in the eyes by flyingglass when a bullet shattered his car window. He was treated at St. FrancisMemorial Hospital and released.

The pursuit began at 4:39 p.m. when police on patrol near the Hall ofJustice at Eighth and Bryant streets saw a Chevrolet Silverado pickup truckrun a red light.

The new gold-colored pickup turned out to have been stolen from a sheriff'ssergeant who was found bound and shot in the back of the head last weekin San Antonio, Texas.

The driver of the truck sped away, starting a chase that zigzagged throughthe South of Market area and the Mission District, with the fleeing suspectsat one point zooming the wrong way on Seventh Street.

The truck made its way back to the Hall of Justice, where it clippedthe building as it went by.

``He obviously didn't know where he was going,'' said Lt. Judie Pursellof the homicide unit.

Mark Brecke, 34, said he was coming out of a bank at Fourth and Brannanstreets when he saw the pickup go by with two dozen police cars behind,the truck's female occupant reloading a gun.

``This is obviously not a red-light runner at lunch time,'` he said.

The pair eventually were cornered on the Embarcadero near Second Street.Police blocked off streets until just before 8 p.m. while they picked upshell casings that littered the South of Market area.


The chase came the same day that authorities in San Antonio said Maxwelland McFarland were being sought for questioning in the slaying of BexarCounty Sheriff's Sgt. Rudy Lopes.

Lopes was 42 and had worked in the county jail for 15 years. His wifereported him missing last week. His body was found in a drainage ditchbehind a mall in San Antonio. His truck and two of his guns were missing.

McFarland and Maxwell had already been charged in Indiana with murder,criminal confinement, arson and theft in the death of 45-year- old RobbyBott, a Federal Express employee who lived in Brooklyn, Ind., south ofIndianapolis. The car in which the two were believed to be traveling wasfound abandoned in San Antonio.


Police Capt. Joel Rush of Speedway, a suburb of Indianapolis, said Bottmay have met his killers through a telephone chat line advertised in publicationssent to local strip clubs.

McFarland danced at Brad's Brass Flamingo, an Indianapolis club. Policesaid Maxwell had been released from prison in January after serving timefor burglary.

``He has never had a job as far as we can tell,'' Rush said. ``He'swhat you call a sponge -- he found women that would just support him.''

McFarland had worked at the club for about three months, said the generalmanager, Don Noe.

``I think they just went crazy,'' Noe said. ``She was never really aproblem when she worked for me. She was like a wild child -- she likedto go out and party, but she always obeyed my rules.

``I think she was led on by him,'' Noe said. ``He just looked like thetype that would do something, but not that bad.''

Rush said Maxwell and McFarland met Bott on Sept. 11, the night beforehe was killed.

The couple came to Bott's home, then went with him to a house in Speedwaywhere Maxwell and McFarland had been staying, police said.

Rush said Bott's home was ransacked and he was forced to accompany thepair on a spending spree, buying jewelry, clothes, lamps and even wastebaskets.

The next morning, authorities found his body stuffed in the trunk ofhis burning car. He had been shot and strangled.

``It was a robbery that went bad,'' Rush said. ``They were trying totake this guy for something, and something must have gone bad.

``They basically set him up,'' Rush said.

Police said they had no idea what led McFarland and Maxwell to headfor San Francisco.

`'They are not world travelers,'' Rush said.

Before fleeing the state, McFarland left her 2-year-old son with hermother in Indianapolis, even signing over legal custody of the boy to herthe day Bott's body was found.

Rush welcomed the capture of the couple. ``I think it's great,'' hesaid. ``I wish we could have gotten to them sooner.''

Pirate Hits Albany, Richmond Police Radios Man taunts dispatchers,calls in phony crime reports

A radio pirate has broadened his invasion of police airwaves, expandingfrom the Berkeley police channel to include Albany, Richmond and CaliforniaHighway Patrol frequencies and using profanity to berate and taunt dispatchers.

So far, authorities have been stymied in their attempts to stop theillegal transmissions, which began earlier this month with false reportsof crimes and are now increasing in vitriol with obscenity-laced tiradesat dispatchers.

``Before, he was just putting out these calls, but now he's really usingthe radio to go off,'' said Berkeley Police Lt. Russell Lopes.

At 9 p.m. Tuesday, a man on the main Berkeley police channel reporteda 10-71, the police code for a shooting, providing a location using streetsthat do not intersect, Lopes said.

A dispatcher recognized the voice from previous incidents and beganreading off a prepared script demanding that he stop using the channelimmediately. The rebuke, first read by dispatchers after a series of breachesby the same man on December 14, only provoked an angry retort by the man.

``B-- can't even read it right,'' he said when the dispatcher falteredat one point.

When the dispatcher warned him that his transmissions were being recordedand passed on to the Federal Communications Commission for possible prosecutionby the U.S. attorney's office, he retorted defiantly: ``Let them recordit.''

When the dispatcher finished, the man waited a few seconds and thensaid, ``What do all that mean? How many years am I facing, I want to know.''

The dispatcher directed officers to go to a secondary police channel.The man said, ``Well, I'll go to channel 2, too.'' He did not, however.There were no further interruptions that night.

The man similarly used obscenities to taunt CHP dispatchers earlierTuesday when he invaded frequencies used by officers in San Francisco andOakland, said Caryl Wilson, a supervisor at the CHP's communications centerin Vallejo.

Wilson said the incidents were mostly nuisances. But officers usinglights and sirens to get to a perceived emergency ``run a risk of endangeringother traffic,'' she said.

``We all take our jobs very seriously,'' Wilson said. ``We want to beproviding the best public service we can. We hate to see risks taken unnecessarilyfor the public, for officers and for ourselves.''

Wilson said, however, that the more the man gets on the air, the greaterthe chance he will be identified with the help of the FCC.

``If he gives them enough, they'll track him,'' Wilson said.

On December 20, the man got on the Berkeley channel and reported an11-99, the police code for an officer needs help. When a dispatcher readthe warning, he said, ``Screw you, b--'' and ``If I get stopped, I'll smokehim,'' apparently threatening harm to police.

The man has also come on the air in Berkeley on at least six other occasionsbeginning on December 12.

Authorities have also reported similar intrusions by the man in Albanyand Richmond.

Police say the occurrences are rare but that anyone with a fair knowledgeof how radios operate could easily penetrate the ultrahigh frequenciesused by many police agencies and the very high frequencies used by theCHP.
