Richard Winfrey, 50, was shot and killed at Gumbiner Park in the 800 block of E. 7th Street in Long Beach on September 25, 2020. Officers arrived about 5:30 a.m. after reports of a shooting and found Winfrey with gunshot wounds to his upper torso; he was pronounced dead at the scene despite life-saving efforts by officers and paramedics.

Long Beach detectives say unknown suspects approached Winfrey in the park and opened fire before fleeing. Investigators linked two men to the case in early 2021: Michael Scott Doss Jr., 29, was charged with murder and held on $2,000,000 bail, and Christian Lucille Watson, 30, was charged with being an accessory to commit murder and held on $1,000,000 bail. Detectives believe the victim and suspects were known to each other and that the shooting grew out of a dispute. Doss also faces an attempted murder count for a bystander, and both men face weapons-related charges.

A neighbor reported seeing a shooter ride up on a bicycle and shoot Winfrey near a park bench. What information can anyone who knew Richard or saw the events that morning add to the investigation?
