A man and a woman have been charged in the slaying of a 50-year-old man in a Long Beach park earlier this year, authorities announced today.

A 29-year-old Long Beach resident named Michael Scott Doss Jr. is facing one count of murder in the death of Richard Winfrey, who was shot to death in Gumbiner Park on the morning of Sept. 25. Doss’ alleged co-conspirator, a 30-year-old woman from Carson named Christian Lucille Watson, is charged with accessory to commit murder, according to court records.

Police said they did not have much information about what sparked the killing other than it was some kind of dispute that escalated into a shooting.

Doss is accused of opening fire on Winfrey in the park at Seventh Street and Alamitos Avenue around 5:30 a.m.

A neighbor who said he watched from his balcony as the shooting unfolded described the killing as “cold blooded.”

The neighbor, who declined to give his name during an interview shortly after the slaying, said the shooter rode up on a bicycle and then killed the victim as he stood with a group near a park bench.

Doss is also charged with a count of attempted murder because of “another bystander in the park that is considered a victim,” LBPD spokeswoman Paige White said.

Police said Doss and Watson knew Winfrey, but they didn’t have any more details on exactly how.

The two suspects have been arrested together before.

On Nov. 19—less than two months after Winfrey’s death—Long Beach officers took them into custody on suspicion of pistol whipping and robbing a man earlier in the day near Ocean Boulevard and Livingston Drive in Belmont Shore, according to the LBPD.

They pleaded not guilty to those charges and were still behind bars when detectives connected them to Winfrey’s killing, police said.

In 2017, Watson and Doss both pleaded guilty to identity theft. She was sentenced to 90 days in jail and three years of probation; he was sentenced to 16 months in jail, court records show.

In the current case, Doss and Watson are also facing charges of illegally possessing a firearm and ammunition, according to records.

Doss is being held on $2 million, and Watson was being held on $1 million bail, police said.
