A look at the Bay Area officers charged with assault, excessive force, death since Oscar Grant

A lot has changed in the world since BART Officer Johannes Mehserle was charged with the death of Oscar Grant at the Fruitvale station in 2009.

At the time, the charges against the former officer were extremely rare. A jury found him guilty of involuntary manslaughter.

In the last 12 years, district attorneys in the Bay Area have charged about a dozen officers for the deaths or assaults on other people, although they have mostly found that the officers' actions in other deadly shootings were justified.

That sentiment changed in the last year or so, as a new California law mandates that prosecutors might find that a police officer's use of force was "necessary" as opposed to "reasonable."

The political climate and the desire to hold officers accountable for their actions has also changed with the May 2020 death of George Floyd at the hands of former officer Derek Chauvin, who a jury in Minneapolis ound guilty of 2nd-degree murder, 3rd-degree murder and manslaughter in April 2021.

Here's a look at the Bay Area officers charged with crimes related to deadly or excessive use of force. In most of the cases, the officers have entered not guilty pleas:

The Santa Clara County District Attorney charged Santa Clara County sheriff's deputies Jereh Lubrin, Matt Farris and Rafael Rodriguez in September 2015 for the murder of bipolar inmate Michael Tyree the month before. Each of the officers was convicted on 2nd-degree murder charges and sentenced in 2018 to 15 years to life in state prison.

Then- San Francisco District Attorney George Gascon in 2016 charged two Alameda County sheriff’s deputies --14-year veteran and training officer Luis Santamaria and 3-year veteran Paul Wieber, who was undergoing field training -- with felony assault after they were seen on video striking Stanislav Petrov, a suspected car thief with batons in the Mission District in 2015. Current San Francisco DA Chesa Boudin quietly dropped all charges in March 2020. Boudin said an expert witness was unavailable because of health issues, and the judge and defense didn't want any more delays.

Also in 2016, Gascon charged San Francisco sheriff's deputies Scott Neu, Eugene Jones and Clifford Chiba with running a jail "fight club." Neu was charged with 17 criminal counts for allegedly forcing at least two jail inmates to fight, gladiator-style in 2015. He was charged with four felony counts of assault under color of authority, four felony counts of making threats, four misdemeanor counts of inhumanity to a prisoner and five misdemeanor counts of inflicting cruel and unusual punishment. However, in 2019 the San Francisco district attorney’s office dropped all criminal charges after prosecutors learned the Sheriff’s Department mishandled the investigation by destroying evidence and improperly conducting joint administrative and criminal investigations.

San Leandro Officer Jason Fletcher was charged in September 2020 for the shooting death of Steven Taylor in a Walmart in April 2020. Alameda County Nancy O’Malley charged Fletcher with voluntary manslaughter, saying he didn't de-escalate the situation.

San Jose police officer Matthew Rodriguez was charged by the Santa Clara County District Attorney in September 2020 with unlawful assault and battery under color of authority after he allegedly kicked a woman in the stomach and dragged her away from a vehicle while she was in handcuffs.

Sonoma County Sheriff Charlie Blount was indicted by a grand jury in November 2020 for the death of David Ward who was driving a car that deputies thought was stolen but actually belonged to him. Blount slammed Ward's head into a car door frame in 2019 and put him in a neck hold after a chase. Ward ended up dying from his injuries. The grand jury charged him with involuntary manslaughter and assault under the color of authority.

San Francisco police officer Christopher Samayoa was charged in November 2020 with manslaughter charges after fatally shooting 42-year-old Keita O’Neil during a 2017 chase. San Francisco District Attorney Chesa Boudin charged Samayoa, with involuntary and voluntary manslaughter, assault by an executive office and negligence discharge of a firearm. O'Neill was unarmed at the time. 

San Francisco police officer Terrance Stangel was charged with beating Dacari Spiers with his baton on Oct. 7, 2019. He was charged in December 2020 with four felony assault and battery charges. 

San Francisco police officer Christopher Flores was indicted by a grand jury in December 2020 on charges of assault with a semi-automatic firearm, negligent discharge of a firearm, and assault by a public officer in connection to his shooting of Jamaica Hampton in December of 2019.

Danville police officer Andrew Hall was charged on April 21, 2021, by the Contra Costa County DA for the shooting death of Laudemer Arboleda, who died November 2018.  He was charged with felony voluntary manslaughter and felony assault with a semi-automatic firearm for the alleged unlawful activity and unreasonable force.
