The Rock Church on Rosecrans Street will be the site of a somber memorial service Friday, Aug. 12 for slain San Diego police Officer Jeremy Henwood, who was brutally shot in the head Saturday in City Heights. Henwood was pronounced dead early Sunday morning. He was killed by a 23-year-old man who was reportedly suicidal. The suspect, who was wielding a shotgun, reportedly surprised Henwood in an apparent ambush while the officer was on patrol. The suspect was later killed in a hail of bullets by police. Thousands of mourners and fellow law enforcement officers are expected to pack the church for the 10 a.m. service. The public is invited to attend to pay tribute. The service will be preceeded by a traditional motorcade of law enforcement vehicles that will begin a 12-mile processional that begins at Qualcomm Stadium in Fashion Valley. — Kevin McKay
