Updated 5:36 p.m. with additional details from press conference.

Investigators say they've determined that a suburban St. Louis woman killed her two young children and herself in the family's Glendale home.

Friday's announcement followed autopsies and several days of investigation by the St. Louis Area Major Case Squad.

Lt. Tim Fagan said at a news conference that 42-year-old Catherine Murch had a history of mental health issues.

Glendale police have called on the Major Case Squad to help investigate a shooting that left a mother and her two children dead in the Glendale neighborhood Monday.

Lieutenant Tim Fagan of the Greater St. Louis Major Case Squad says the investigation is fluid and he says authorities will work the theory that it was a murder suicide.

But Fagan says he isn’t willing to rule out any scenario.

“We haven’t come to what would be a full conclusion as to what would have happened,” Fagan said.  “The totality of the circumstances, I don’t have everything I need at this time.”
