Freemason kills mom with ceremonial sword.

Maybe he saw the fnords. From the NY Post:

An actor who had a part in "Ugly Betty" repeatedly stabbed and killed his mother with a Freemason ceremonial sword this morning, cops said.

Yannick Brea, 55, was found in her second-floor Brooklyn apartment around 2:20 a.m. with multiple stab wounds. Her son, Michael Brea, 31, was taken into custody and then to Kings County Hospital, where he is undergoing psychiatric evaluation.

Cops were called to a domestic disturbance at the home earlier in the evening but left shortly thereafter. Neighbors Vernal Bent and his mother Phyllis said they heard yelling from the floor below between 1 a.m. and 2 a.m. and called 911.

"I heard a shriek and a woman yelling 'help me'," Vernal Bent said. "We called 911 and we kept hearing screams and then we didn't hear them any more. Michael was chanting Biblical phrases and kept calling for Moses, Jerusalem and the 'architect of the universe'."
