He remained hospitalized at Highland Hospital on Friday as police continued investigating the incident at a Chevron Station just off Interstate 980 near downtown Oakland. Surveillance video captured a harrowing scene: Three assailants ambushed and robbed Joyner as he pumped gas into his Porsche; Joyner pulled out a gun and shot two of the attackers — one fatally — before he was shot as the two jumped in their car and fled.
Police have not made arrests in this case or identified the assailants.

In a city jolted by gun violence, the incident stunned those who knew Joyner as a cop who had been so instrumental in fighting crime and counseling youth. Suddenly he had become a crime victim himself.
Born and raised in East Oakland, Joyner joined the police force in 1991 with notions that he would change the corrosive relationship between officers and the communities they served, said Regina Jackson, CEO of the East Oakland Youth Development Center and president of the city’s Police Commission.
“He told me the reason he became a police officer was because he didn’t like police officers,” Jackson said. “He wanted to be the one who was more engaged and made people not dislike police officers.”
Joyner had a mission to set youth “on the right track,” Jackson said, and helped mentor teenagers at the East Oakland center and similar organizations. But he was also known for being aggressive and ambitious.
After starting out as an undercover narcotics officer, Joyner eventually switched to the SWAT team. He cannily worked sources for information, including location of parolee and rape suspect Lovelle Mixon, who killed four Oakland police officers and then died in a shootout with police in 2009.
“He’s from Oakland, he’s well known in Oakland — that brought a lot of credibility,” said David Muhammad, a former Alameda County Chief Probation Officer and criminal justice reform consultant who has worked closely with Joyner for a decade.
At the same time, Muhammad recalls Joyner voicing regrets about his actions as a beat cop in the early 1990s. Mostly, Muhammad said, he had misgivings about the number of arrests he made as part of the War on Drugs.
He rose up the ranks, becoming a lieutenant in 2006 and overseeing the homicide unit, where, according to a biography on his booking website for public speaking gigs, he supervised 373 murder investigations and 30 shootings by police officers.
In 2009, Joyner continued his ascent, first as a commander in the Bureau of Field Operations and then to captain in 2010. He came under scrutiny the following year, after he and another officer fatally shot two men they believed were headed to commit a murder. Prosecutors cleared the officers of potential charges and the families sued Oakland for wrongful death, leading the city to pay a $75,000 settlement in 2016.
Several law enforcement and city sources have said Joyner had fraught relationship with court monitor Robert Warshaw, who for years has overseen mandatory reforms in the city’s Police Department, stemming from a landmark civil rights settlement in 2003.
Joyner himself had harsh words for the monitor in a 2020 interview with the Chronicle.
“Warshaw, for whatever reason, has treated the city of Oakland as his personal annuity,” he said. “There’s a saying, that if you’re teaching a class and five people fail, they didn’t study. If 20 people fail, you didn’t teach.”
Even as he held a high position in the police department, he maintained ties in his community.
Reygan Cunningham, who worked with Joyner for years, remembers marching with him through East Oakland, after the murder of three-year-old Carlos Nava in 2011.
“I had never been out in the community with a cop where people came out of their houses to acknowledge him and say ‘What up E,’ ‘How you doing Ersie?’” Cunningham recalled.
In 2013 the department tapped him to head Ceasefire, Oakland’s flagship violence prevention program that had limped along since its inception in 2007, viewed during that period as a low priority. Joyner steered it through a phase of expansion, in which the city beefed up staff and began its targeted interventions with suspected gang members. Joyner and other officers began doing “custom notifications,” in which they would visit potential recruits to the program as soon as they were released from jail, usually accompanied by a pastor.aside">
