14-year old California boy shoots and kills father, an Immigrations Officer

Myron W. Chisem, a U.S. Immigration and Customs Enforcement officer, was in his Los Angeles home at night when a bullet came through the window from outside, striking and killing him.  It was shot by his 14-year old son using the officer's service handgun.  By all accounts, there hadn't been any problems between the two prior to that point.

From the article:

 The 14-year-old was doing well in school, loved playing video games, and even visited the library with Chisem every so often, said Shawn Butler, Chisem's friend.

"In his eyes, everything was peachy, lovely," Butler said.

But late Wednesday, authorities said, the 14-year-old fatally shot his 42-year-old father, striking him once in the head from their Carson backyard as Chisem sat in the family room. The son called 911, Los Angeles County Sheriff's Department officials said, and deputies found Chisem's ICE-issued handgun in the frontyard. About eight hours later, the teen was arrested and booked on suspicion of murder.

"This was a domestic violence incident," Lt. Holly Francisco said. Authorities did not identify Chisem's son and said the motive was unclear.

Butler, 41, met Chisem in naval training in 1991 and served with him as a member of ICE. He said there "was never any indication" of trouble between Chisem and his son. He said the boy had moved in with his father less than a year ago after a family agreement.

"They had a great relationship," Butler said. "He was very proud of his son. He loved him very much.... All the time I had been around them I had never seen any kind of issues of tension between them."

Every gun in the hands of a child must first pass through the hands of an adult.
