Jamal Cheeks, 21, of Oakland, California, was fatally shot in the neck on October 31, 2014, about 3:55 p.m. at a home in the 2000 block of 22nd Avenue. The shooter was identified as his best friend, 20-year-old Damian L. Joseph. Joseph told police he was playing with a semi-automatic pistol he believed to be unloaded when it discharged, killing Cheeks.

Joseph was initially charged with murder. He later pleaded no contest to involuntary manslaughter on April 27, 2015, acknowledging reckless conduct rather than intent to kill. During sentencing proceedings he read an apologetic letter and showed remorse; his attorney noted no prior record and letters of support. On June 12, 2015, Alameda County Superior Court Judge Paul Delucchi sentenced Joseph to five years in state prison.

What additional details does anyone have about the events that day or about the two men involved?
