Myron Chisem, 42

Myron Chisem, a 42-year-old black man, was shot and killed Wednesday, May 2, in the 19300 block of South Broadacres Avenue in Carson, according to Los Angeles County coroner's records.

The victim was a Navy veteran who had been an Immigration and Customs Enforcement agent since 2007.

Chisem was pronounced dead at the scene of the shooting, which occurred shortly after 9 p.m. at his home, according to the Los Angeles County Sheriff's Department.

Lt. Holly Francisco said Chisem's son, whose name hasn't been released, is alleged to have fired one shot from the backyard with his father's ICE-issued handgun.

The victim was in a TV room on the ground floor when he was wounded in the head, Francisco said.

The agent's girlfriend also lived at the house but was not there at the time of the shooting, authorities said.

The boy, who is 14, was apprehended and arrested in connection with his father's death.

He did not enter a plea to a murder charge at his initial juvenile court appearance May 7 and will face a May 21 hearing on his fitness to be tried as an adult.

Authorities say the boy was upset after clashing with his father over his school grades.

“There were some disciplinary issues in the house of which grades was one of them,” Deputy Dist. Atty. Todd Hicks told KTLA-TV.

The teenager called 911, but officials have not said if he told dispatchers that he had shot his father. Deputies found Chisem’s handgun in the front yard.

Longtime family friend Shawn Butler said last week that there “was never any indication” of trouble or tension between Chisem and his son, who moved in with him less than a year ago.

“They had a great relationship,” Butler said. “He was very proud of his son. He loved him very much.”

Anyone with additional details about the killing is asked to call the sheriff's homicide bureau at (323) 890-5500. Those wishing to remain anonymous may call Crime Stoppers at (800) 222-8477.
