OAKLAND -- The "shiny object" police officers said they saw Derrick Jones holding as he ran before he was fatally shot Monday night was an electronic scale, police said Friday.
Police also said a small amount of marijuana was found in one of Jones' pockets.
The unarmed 37-year-old, a father and barbershop owner, was fatally shot by two officers after a brief foot chase. The officers were trying to detain him after a report of a domestic dispute. A woman who told police she was Jones' girlfriend said he had beaten, choked and threatened her at the barbershop. Jones was on parole, police said.
People who know Jones have said it was the woman who attacked him.
But a domestic violence call should never have ended in the shooting of an unarmed man, Jones' family, friends and supporters said Friday afternoon at a rally held outside his barbershop, Kwik Cuts, on Bancroft Avenue.
The crowd held signs reading, "A badge is not a license to kill."
"I'm not surprised a black man was killed. I'm just surprised that it keeps happening and we can't do anything about it," Qadree Carminer said. He is one of a tight group of friends that included Jones.
It was during the rally Friday that sources identified the officers involved as Eriberto Perez-Angeles, who has been with the department for three years and is also a member of the SWAT team, and Omar Daza-Quiroz, an officer for four years.
The officers told investigators that Jones kept reaching toward his waistband and that at one point they saw a "shiny object" that turned out to be the scale. Police said such scales are often used to weigh drugs.
Oakland civil rights attorney John Burris, who has consulted with Jones' relatives, was skeptical of the explanation.
"For one thing, I'm surprised it's taken five days for the police to reveal this information," Burris said. "And the fact that they saw something shiny was certainly not a basis to shoot and kill someone."
Officers told investigators they shot Jones after he refused their repeated commands to raise his hands. An autopsy determined Jones was hit several times in the front, at least twice in his upper body.
No gun or other weapon was found on him. The scale was found alongside his body, authorities said.
Oakland police spokesman Officer Jeff Thomason on Friday described the scale as 3 inches by 5 inches with a silver finish. The marijuana was found in a small glass container.
Neither the officers nor their attorney could be reached for comment.
The police homicide and internal affairs units and the Alameda County District Attorney's Office are investigating the shooting. The two officers are on paid administrative leave, routine after an officer-involved shooting.
A march Thursday from the barbershop to the Fruitvale BART station was peaceful but closed down the BART station for about an hour. Friday's rally on Bancroft Avenue also ended peacefully at 5 p.m.
"All police aren't bad," said J.B. Jones, a pastor with the Alfa Omega Worship Center on International Boulevard. "But the system is."
After the rally ended, Michael Jones, 32, brother of Derrick Jones, was arrested several blocks away on suspicion of driving under the influence of alcohol. Police also arrested two other men, Tiu Ogbemudia, 32, and Manuel Padilla, 32, in the same silver Honda Accord. All three were taken to the Glenn E. Dyer jail in Oakland.
Police said they weren't aware of Michael Jones' identity until after the arrest.
