The 15-year-old girl remained hospitalized Thursday in critical condition. Police have arrested Katie Stay's former brother-in-law, Ronald Lee Haskell, 33, in connection with the killings. He recently lived in northern Utah, where he had a history of domestic violence.

MENIFEE, Calif. — The grandmother of a 15-year-old girl who survived her family's massacre in Texas says the teen saved lives by warning police.

Joyce Stay of Menifee, California told the Riverside Press-Enterprise Thursday that Cassidy Stay is out of critical care.

Ronald Lee Haskell was arrested Wednesday in Houston for allegedly killing six members of his ex-wife's family, including four children. Cassidy was wounded but played dead, then warned police that Haskell planned to shoot other relatives.

Cassidy's parents and four siblings died. They originally were from Southern California.

Joyce Stay says the last she'd heard of Haskell, he was living in Southern California, wasn't eating and wouldn't get out of bed.

Stay says the next thing she heard was a phone call saying he'd wiped out most of her family.
