Thong Kien Ma, 32

 Thong Kien Ma, a 32-year-old Asian man, was shot and killed by Los Angeles County sheriff's deputies Tuesday, May 5,  in the 10400 block of Enloe Street in South El Monte, according to the L.A. County coroner's office. 

Ma was attacking his neighbor with a meat cleaver when Sheriff's Department deputies arrived at the residence, according to a news release from the department. The deputies fired when Ma came at them with the cleaver, investigators said. 

When the first deputy arrived about 12:47 p.m., he saw Saney Ngo, 55, an Asian woman who was standing in the street outside her home, bleeding from the head. 

The deputy then noticed the suspect standing in a flower bed outside the front door of the residence. He appeared to be repeatedly hacking at something, according to the news release. 

The deputy moved closer and realized the suspect was hacking at a man — Ngo's husband — with a meat cleaver. 

Investigators said the deputy immediately ordered the suspect to stop and drop the meat cleaver. The man did not comply, they said.  Instead, he raised the cleaver and ran toward the deputy, who shot him. 

After the shooting, the man stopped attacking Chau Da Ngo, 59, but did not drop the cleaver, investigators said. When a second deputy arrived, the man allegedly charged both deputies with the meat cleaver still in hand, and the deputies shot him again.

Investigators said the second shooting stopped Ma, who was pronounced dead at the scene at 1 p.m.

Chau Ngo was also pronounced dead at the scene at 1 p.m. His wife was treated for head lacerations at a local hospital and released.

The deputies were not injured. Neither deputy has been identified. 

Investigators said Ma was displaying delusional and erratic behavior during the attack.
