One or more burglars struck an Oakland elementary school over Labor Day weekend and stole nearly all of the school’s Google Chromebooks. It was the latest in a string of break-ins resulting in the loss of hundreds of thousands of dollars worth of equipment at the Oakland Unified School District, officials said.

Seven classrooms in Markham Elementary School, including three with carts full of laptops used for instruction and testing, were burglarized, district spokesman John Sasaki said. The burglars took about 60 computers, leaving behind at least one that was broken.

“Anytime you are taking anything from our schools, you are taking from our kids,” Sasaki said. “These are really important tools.”

This wasn’t the first looting of tech at Markham.

Someone broke in last winter and stole 40 Amazon Kindle Fire e-readers and 25 accompanying headphones, officials said. When they heard about it, Amazon officials sent the school replacements.

Sasaki said the district is still taking inventory of equipment and has alerted local used-goods businesses to be on the lookout. The school has serial numbers for all of the Chromebooks.

It’s unclear when the break-in occurred and how many people were involved. Police were looking through surveillance video.

Thieves have recently targeted other schools in the district, Sasaki said. No one has been arrested in any of the incidents.

Internal Affairs clears S.F. officers in fatal 2015 shooting

The San Francisco Police Department’s Internal Affairs Bureau found that two officers acted within policy more than four years ago when they fatally shot a knife-wielding man in the back and side after a confrontation over a bicycle in the Mission District.

The department released more than 700 pages of documents Wednesday in the investigation into the shooting of 21-year-old Amilcar Perez-Lopez. Officer Eric Reboli and Sgt. Craig Tiffe were within policy when they shot the Guatemalan immigrant six times on Feb. 26, 2015, the probe found.

The district attorney’s office in 2017 declined to file charges, citing insufficient evidence that the officers broke any laws in the killing that sparked outrage among community groups. The city last year agreed to pay Perez-Lopez’s family $275,000 to settle a civil lawsuit.

Wednesday’s documents, which include Internal Affairs Bureau and Homicide Bureau reports, along with Police Commission recommendations and transcripts of interviews with the officers, were released under the police transparency law SB1421, which took effect Jan 1.

While the investigation found the officers’ actions met policy standards, the department determined Tiffe had failed to bring his department-issued pepper spray, an impact weapon and a spare magazine when he approached Perez-Lopez.

Chief Bill Scott ordered Tiffe to be admonished for the lapse and retrained. The order did not constitute discipline, according to the report.

Both officers have returned to duty.

The shooting came amid a wave of police killings — including the Bayview shooting of Mario Woods in December 2015 — that led to the ouster of then-Chief Greg Suhr and prompted a Justice Department review of the Police Department.

Just before 9:45 p.m. the night of his death, Perez-Lopez, armed with a large kitchen knife, was chasing a man down the street, prompting a witness to call 911, officials said. Perez-Lopez and the other man had either been arguing over the sale of a bicycle, or the confrontation erupted in a nearby apartment where Perez-Lopez grabbed the knife, according to investigators.

Reboli said he was protecting himself and his partner, while Tiffe said he had fired believing Perez-Lopez was going after the earlier victim with the knife. An attorney for the family said Perez-Lopez was intoxicated, didn’t realize the plainclothes officers were police, and was trying to force them back before he took off running.

According to the medical examiner’s report, five of the bullets struck Perez-Lopez in the back and one struck him from left to right.

A use-of-force expert retained by the district attorney’s office said it was possible Perez-Lopez had faced Reboli when Reboli began to shoot, only to turn and receive the shots in the back.

Bay Area fire crews offer help during Hurricane Dorian

Oakland and Menlo Park firefighters have been among the thousands of responders providing assistance as Hurricane Dorian pelts the East Coast.

As of Friday, crews from the Bay Area were stationed in North Carolina, where high winds and heavy rainfall were expected to cause catastrophic damage.

Task forces sponsored by the Menlo Park Fire Prevention District and Oakland Fire Department are among the seven groups tapped by the California’s Office of Emergency Services, state officials said.

Menlo Park’s contingent of 45 people and three dogs flew to Charlotte, N.C., on Wednesday morning to assist with search and rescue operations, while Oakland’s group, about 35 strong, touched down in Charlotte that morning.

California Gov. Gavin Newsom approved the deployment of five urban search and rescue task forces and two water rescue teams to support first-response operations as Dorian approached early last week.

Other personnel included members of the Sacramento Fire Department, the Oakland Fire Department, Los Angeles Fire Department, San Diego Fire-Rescue Department and Cal OES Fire and Rescue, according to a news release from the state Office of Emergency Services.

The Menlo Park task force sent an additional 10 civilians, including doctors, structural engineers and hazardous material workers.

On Thursday morning, the Menlo Park group unloaded search and rescue, medical, decontamination and other gear and equipment that was airlifted from Oakland, said Menlo Park Fire Chief Harold Schapelhouman.
