Detectives revealed the image of a person of interest Tuesday in the fatal shooting of a 27-year-old father of two in Hacienda Heights more than 12 years ago.
She went to the house to check on Berber because she had not heard from him for several days, the Los Angeles County Sheriff’s Department stated in a news release.
His mother found out that Berber's employer had not been able to contact him either.
Berber's body was found in his bed and investigators believe he was fatally shot in his sleep, Sheriff Jim McDonnell said during a news conference Tuesday.
A sketch of the person of interest, which was created to show what the person would have looked like at the time of the crime, was displayed during the news conference.
Investigators are hoping that advancements in forensic science and new testing will help jump-start the investigation and potentially identify a suspect or suspects.
“We believe that we are very, very close to a breakthrough in this case,” McDonnell said.
Berber was the father of a 3-year-old and an 8-year-old when he was killed.
The children were not home during the shooting because they were with Berber's estranged wife at the time, McDonnell said.
Berber was described by his sister as a family man who had a master's degree from Notre Dame.
"He set goals … I wished I could be like him," she said.
A $10,000 reward has been approved for information leading to an arrest in Berber's killing, McDonnell said.
Anyone with information was asked to contact the Sheriff's Department at 323-890-5500 or Crime Stoppers at 800-222-TIPS (8477).
