A $50,000 reward was offered Tuesday for information leading to the arrest and conviction of the suspect responsible for fatally shooting a man in his back as he crossed a street in South Los Angeles.

Family members and business colleagues attended a news conference at which Councilman Bernard Parks and top police officials investigating the case discussed the shooting Wednesday at 10:40 p.m. of 31-year-old Herbert Eugene Seymour.

The victim was walking home from a liquor store near 105th Street and Western Avenue.

Seymour worked for Best Buy and was reportedly well liked by his coworkers.

Seymour collapsed in the middle of the street and was pronounced dead at the scene.

The suspect was described as being in his late teens to early 20s. The motive for the killing is unknown.

Anyone with information about the killing was asked to call 77th Division gang and homicide Detectives Eric Crosson or Sam Arnold at (213) 485-1383.
