Seymour was shot and killed at 104th Street and Western Avenue, less than a block from his South Los Angeles home, on Feb. 9 while he was crossing the street at about 10:40 p.m. Detectives believe a suspected gang member walked up behind him and shot him several times in a completely unprovoked attack.
The 31-year-old father of two was very popular with his co-workers at Best Buy. Police say he had no gang affiliation, but there has been a gang feud in the area where he was shot and killed. Police believe he was killed because he was mistaken for a gang member.
"He was a good kid. We never had any trouble out here at all, so for this to be a gang shooting, it's just unbelievable, it's unbelievable to us," said mother Cynthia Seymour.
Seymour's family joined police at a news conference on Tuesday to announce the reward for information leading to the arrest and conviction of his murderer.
Authorities believe there were witnesses in the area at the time. Police and Seymour's devastated family urge anyone who has information to come forward.
"We lived at that house for 30 years. He never ever hurt anybody, so please, if you have any information, would you please help us with this?" said father Herbert Seymour Sr. "Our hearts are broken. We lost a loved one."
If you have information you think could help police catch his killer, you can call the LAPD anonymous tip line at (877) 527-3247.
The family plans to hold services for Seymour on Friday.
