Los Angeles County Sheriff's Department held a press conference announcing the reward and provided details about the circumstances surrounding the deaths of Walter Vicente, 49, and Andrew Vicente, 24.

Detectives believe someone with a shotgun entered the home and fatally shot the two men. Coroners said the two men were shot in the head.
Detectives added that there were no signs of forced entry into the home.
Authorities have not made any arrests in connection with the fatal shooting.
"The detectives have yet to identify a motive for the killing and have exhausted any of the credible leads," said Dave Coleman of the Los Angeles County Sheriff's Department.
The Los Angeles County Board of Supervisors and the City of Norwalk were offering a combined $20,000 reward for information leading to an arrest and conviction of the person or people responsible for the killing, according to a news release.
The mother of Andrew and ex-wife of Walter, made an emotional plea at the press conference, urging the public to help detectives find their killer.
James Vicente, the victim's brother, read a statement for the mother, saying "Neither one of them deserved this and we are here pleading for any information regarding this case."
"What had happened to them should not happen to anybody or any family. We need your help in getting information to help find the people responsible for taking two lives away," he said.
Detectives said they could not find any business disputes or vendettas that could hint to a motive.
Anyone with information was asked to call the Los Angeles County Sheriff's Department at 323-890-5500.
