"Ugly Betty" actor Michael Brea confessed to hacking his mother to death with a sword in an interview with The Daily News, the paper reported.
"I didn't kill her. I killed the demon inside her," he said in the interview, conducted Thursday in the prison yard of New York City's Bellevue Hospital.
Yannick Brea, 55, died Tuesday.
"So be it. It was the work of God," Brea, 31, told the paper.
In the interview, Brea talked about a descent into a world of Masonic symbolism and black magic. He said he suddenly awoke Sunday to find God above his bed, reaching out his arm.
"I said, 'God, is my time on earth over?' I heard a voice say, 'Yes Michael, today is your last day.' I asked if I could say goodbye to my family."
He said he received another sign Monday at Harlem's Prince Hall Masonic Temple, when a man tried to put a curse on him. He said the man kept trying to give him a Freemason pin, which he refused to accept. He later took a train to Brooklyn, he said, and strangers began speaking about his mother.
"I felt like Neo from 'The Matrix.' I began hearing voices and feeling powerful," Brea said. "They were asking about the difference between mom and mother. It was a sign."
When he got home, he hugged his Haitian immigrant mother, because ""I knew I would never see my mother again," he said. "I gave her lots of love."
He went to his room, lit candles and used a 3-foot ceremonial Freemason sword to attack. It was earlier reported to be a samurai sword.
"I asked, 'Do you believe in God?' She said, 'No, Michael no,' and began screaming. I began slashing her like this," he said, imitating a hacking motion.
Brea said he is convinced he did the right thing.
"Grand Architect of the Universe means God," he told the paper, repeating an expression neighbors said he shouted as police removed him from the scene. "I was praising God. To you it might sound silly, but in my culture demons are very real."
Brea had supporting roles on "Ugly Betty" and "Step-Up 3D."
