Simpson posted a Facebook Live from her hospital bed Wednesday in which she detailed her injuries and the loss of her three children. The ex-wife was the only person who survived the murder-suicide.
"The shooter was a male", Hinojosa said.

The Denton County Sheriff's Department is helping the Ponder Police Department investigate the case.
"My prayers are with our community and each of you", Yeager said in a statement released to parents in the district.
"I want to pray for the victims of the deceased family", Hinojosa said, according to the Dallas Morning News. "So, residents of the Ponder are safe", he said.
Fire officials in Ponder, 30 miles (50 km) north of Fort Worth, told NBC 5 that five people were found dead inside the home and the shooter was among the dead.
"I have to start funeral arrangements and don't know where to begin with that", said Simpson in an emotional post.
"That's always a bad thing to hear no matter who the family is whether she you know them or not, somebody to be in that much pain", neighbor Diana Booker said. She said she'd been in the area for 16 years.
