George Hang, 17

George Hang, a 17-year-old Asian teenager, was shot and killed Monday, July 27, in the 8700 block of Valley Boulevard in Rosemead, according to Los Angeles County coroner’s records. 

The investigation began about 10:10 a.m., when the Los Angeles County Sheriff’s Department received a 911 call from a woman saying she had shot her son, according to coroner’s records. 

Lt. Victor Lewandowski said the mother and her son lived in a residence in the city of Rosemead but had checked into the Valley Hotel the day before the shooting. “I can’t get into the reasons why, or discuss anything about her physical or mental health,” Lewandowski said. 

Investigators learned that some guests in the hotel had heard gunshots about 5 a.m. but didn’t report them, he said. 

Hang was found in the hotel bed and pronounced dead at the scene at 10:15 a.m. with a gunshot wound to the chest, according to coroner’s records. A handgun was found at the scene. 

His mother, Lai Yeung Hang, a 49-year-old Asian, was arrested on suspicion of murder and booked into jail in lieu of $2-million bail. 

Lai Hang was charged with one count of murder July 30. She is accused of shooting her son with a handgun while he slept, according to a news release from the Los Angeles County district attorney’s office. She is scheduled to be arraigned on Aug. 12 in Department D of the Los Angeles County Superior Court, Pasadena Branch.

Anyone with information is asked to call the sheriff’s Homicide Bureau at (323) 890-5500. Those wishing to remain anonymous should call Crime Stoppers at (800) 222-8477.
