A Salt Lake man who police say killed his wife during a family fight and then shot himself in the head has died.

Jerry Lyday, 57, died at 11:02 a.m. Sunday in LDS Hospital's intensive care unit, where he had been on life-support systems since the shootings Saturday afternoon, Salt Lake Police Lt. Mark Zelig said.Zelig said no further investigation was under way Sunday and a decision about whether to officially declare the shootings a murder-suicide would be made Monday.

"There probably will not be a whole lot of additional investigation conducted," he said. "It's pretty clear-cut he was the assailant based on what witnesses have told us."
