The man suspected of killing Mendocino County reggae musician Jamal Andrews had a history of aberrant behavior, according to Mendocino County court records.
"He is mentally ill and extremely unstable," Billy Norbury's estranged wife, Brittany, wrote in a May, 2011 letter to the court explaining why she wanted custody of their three children and wanted her husband limited to supervised visits.
Norbury, 33, is in Mendocino County jail in connection with the shooting death of Andrews, 30, Tuesday night outside the victim's home. It was the third time Norbury had made a late-night visit on an all-terrain vehicle to the home Andrews shared with his long-time girlfriend, Miranda Mills, and their 8-month-old son, Kaiden.
Mills, her voice breaking with emotion, said Thursday she went outside following the shooting.
"Jamal passed away in our front yard while I was holding him," she said.
An autopsy determined Andrews was shot in the head and shoulder.
Mills said they had not met Norbury before he showed up inexplicably at their house about three months ago and she does not know what prompted his actions.
"I wish he would tell us why," she said.
Mendocino County Sheriff's Capt. Kurt Smallcomb said Thursday that a motive for the killing has not been determined.
Norbury's wife said in court affidavits that he is irrational and suffers from paranoia. He thought people were following him and listening to his conversations through the television, phone and car radio.
