Anthony Mancilla was riding his bike home from a convenience store on Tuesday evening, when gunfire erupted along Senter Road.
He saw a lot of police officers, "more than normal," and heard two gunshots - one of them that ended up fatally hitting Officer Michael Johnson, a 14-year-veteran of the San Jose police force and the first to die in the line of duty since 2001.
Mancilla took out his cell phone and took some video. The scene showed San Jose police cars lined up along Senter Road. A horn blared. People walked up and down the street. One man said "He shot a cop. He shot a cop." Another man said: "He's f---ing dead. Oh my God."
NBC Bay Area is not showing the entire video because it is laced with expletives and shows the officer's body down on the street.
Johnson was killed by 57-year-old Scott Dunham of San Jose, who Police Chief Larry Esquivel described as “despondent” when family members called for help about 6:48 p.m. Tuesday, police said. When Johnson arrived to help, police say Dunham fired at him from his apartment balcony in the 2600 block of Senter Road. Johnson died at the scene.
On Wednesday morning, Police Chief Larry Esquivel said that Dunham was found dead on the balcony about 3:20 a.m. He had suffered at least one gunshot wound. It's still unclear, however, if he killed himself, or if he died as a result of the ensuing police gunfire.
