Joseph Ash, 18, was shot and killed on November 1, 2020, at an apartment in Sacramento where he and a friend, Micah Nero, were hosting a party. The gathering had been advertised on Snapchat and was open to the public. Granderson returned to the apartment, knocked, and when Ash and Nero answered, Granderson opened fire, fatally wounding both teenagers.

Sacramento Sheriff’s Office homicide detectives later identified Granderson as the shooter and he was arrested in Las Vegas more than six months after the killings. A jury convicted Andrew Granderson of two counts of first-degree murder, with gun use enhancements and the special circumstance of multiple murders, and he was sentenced to life without parole.
