Gary Scott Holland, 43, was arrested in connection with the October 29 bludgeoning murder of Kathleen "Kate" Horan. District Attorney Kamala Harris labeled Holland, currently being held at the psychiatric ward of the San Francisco Jail, a "true predator." How so? Using residual fears stemming from September's San Bruno blast, Holland allegedly "went knocking on doors posing as a gas worker" until he found a victim

"In that way, the defendant was a true predator and put himself out in a position of trust so that she opened that door," Harris told The Chronicle. "Let us all sleep well knowing he is captured."

SFPD said the victim fought back, scratching her attacker, before her death.

Holland was "charged today with murder, attempted rape and robbery."
