More than a decade after the BART police killing of Oscar Grant, the transit agency has released a long-sealed report on a shooting that shocked the Bay Area, led to a rare criminal conviction for an officer's use of force and heralded a national movement for police accountability.
The 94-page report released Tuesday shows that investigators questioned Officer Johannes Mehserle's explanation for the New Year's Day 2009 shooting — that he meant to draw a Taser, not his service firearm, before firing the round that killed Grant.
The document also lays much of the responsibility for the incident, which occurred after BART police responded to a report of a fight on a train, on a second BART officer — Anthony Pirone. The report says Pirone, who punched and kneed Grant after detaining him, "started a cascade of events that ultimately led to the shooting."
The report, completed by independent investigators hired by BART in July 2009, was released by the agency Tuesday under terms of SB 1421, California's new police transparency law.
Sections of the report relating to Mehserle were redacted, and investigators noted they had been unable to interview the officer.
But they wrote that videos of the Fruitvale Station incident showed Mehserle may have known he was drawing his firearm, not his Taser, before shooting Grant.
"Despite the inability to interview Officer Mehserle, the conclusion can be made from a close viewing of the enhanced video that he was intending to pull his firearm and not his Taser," the report says, noting that Mehserle repeatedly reached for his gun "and on the final occasion can be seen looking back at his hand on the gun/holster to watch the gun come out."
Mehserle fired a single round into Grant's back.
Just prior to the shooting, the 22-year-old Grant, face down on the station platform with Officer Pirone kneeling on his neck and head, had put both hands behind him "in a handcuffing position," the report says.
"Deadly force was not justified under the circumstances," the investigation found.
