Texas mom Christy Sheats, who was killed by police after slaying her two daughters last week, had a history of mental problems.
Moreover, she reportedly owned several guns.
It was a horrific scene at a family birthday party as the mom fatally shot her two girls before she was gunned down by police.
Christy, 42, reportedly exploded with rage, firing at her daughters Madison, 17, and Taylor, 22, as they fled into the street.
Her husband could be heard pleading: "Don’t do this! They’re our kids!" Now he is left to cope with unimaginable tragedy.
