Superior Court Judge Bill Bowman ordered that Michael LaRosa remain at Western State Hospital, a psychiatric facility where he's spent much of his time since his arrest.
LaRosa had been charged with first-degree murder in the deaths of 58-year-old Joseph LaMagno and 64-year-old Dale Richard Holme. The men were attacked one day apart.
In a recent ruling after a bench trial, the judge found that LaRosa had killed the two men but was insane at the time. Bowman also found that LaRosa presents a "substantial danger" to public safety.
LaRosa's family has said he had long suffered from mental illness before the unprovoked slayings.
