Tyshawn Powell, 20, was found unresponsive in the driveway of his Paradise Hills home on the 6200 block of Childs Avenue in San Diego on June 29, 2019, and was pronounced dead after officers and paramedics arrived. The cause of death was multiple gunshot wounds, including at least one fatal shot to the head.

Investigators say an argument that morning between Powell and 19-year-old Angelo Roshon Richardson Jr. escalated and Richardson fired multiple shots at Powell. Several rounds also struck Powell’s house while family members were present. Richardson fled but was arrested nearby; he was found with a firearm and was on probation for a 2018 felony robbery. Authorities charged him with murder, shooting at an inhabited dwelling, possession of a firearm, and being a prohibited person in possession of ammunition, and he was held on $2 million bail. Eighteen-year-old Mikayla Ann Castillo was charged with being an accessory to murder and carrying a concealed weapon and was released on bail pending further investigation.

Family and community members set up a memorial outside Powell’s home. Anyone with information is asked to contact the San Diego Police Department’s Homicide Unit or Crime Stoppers.
