Billy Norbury suffered from paranoid-type schizophrenia when he killed a Mendocino County reggae musician early this year, a psychiatrist testified Tuesday during the defense portion of Norbury's murder trial.
"He was very paranoid and easy to anger," Dr. Donald Apostle said in Mendocino County Superior Court.
Norbury also was highly intoxicated, with a blood alcohol level estimated at more than twice the legal limit when he shot and killed Jamal Andrews, according to court testimony.
He has entered pleas of not guilty and not guilty by reason of insanity.
Apostle said Norbury was delusional, narcissistic, suffered from hallucinations, was pathologically jealous and believed there were multiple plots against him.
For some unknown reason, Norbury apparently made Andrews, a neighbor in rural Redwood Valley, one of the characters in the plots, he said.
Norbury told members of his family, "that black man down the road is doing voodoo on me," Apostle testified.
Norbury also had accused his wife of having an affair with Andrews and believed the Andrews may have turned him in to police for growing marijuana, according to court testimony.
His wife had never met Andrews and Norbury was not under investigation, according to earlier testimony.
Norbury's estranged wife, family members and a member of the Mendocino County drug task force were among those Norbury thought were plotting against him.
