Authorities in Texas said Monday the woman who killed her daughters called a family meeting before the shooting began.

Fort Bend County Sheriff Troy Nehls said a family argument led to the shooting Friday evening at a home outside the Houston suburb of Fulshear. Christy Sheats, 42, convened the meeting in the living room of the home that was attended by her husband Jason Sheats, and her daughters, Taylor Sheats, 22, and Madison Sheats, 17, according to the sheriff's office.

"During that meeting, Christy Sheats held up a gun and shot both girls," the sheriff's office said.

Jason Sheats and the daughters ran outside where Madison Sheats collapsed and died. Jason Sheats ran to the end of the cul-de-sac.

Christy Sheats shot Taylor Sheats one more time on the street. A witness told investigators Christy Sheats then went back into the home, reloaded her gun and shot Taylor once more.

When officers arrived, they saw Christy Sheats shooting one of her daughters in the street, the sheriff's office said.

An officer fatally shot Christy Sheats after she refused to obey commands to drop her handgun. Taylor Sheats was taken to a Houston hospital, where she died.

A Facebook profile consistent with Sheats' biographical details included a pro-gun post, alongside posts about how much she loved members of her family.

Madison Davey, a friend of the Sheats daughters, told KTRK-TV that the two girls were caught up in the troubled marriage of their parents. She said that Jason Sheats told her that Christy Sheats shot her daughters because she wanted him to suffer.

Davey also said that the weapon used in the murders was passed down from Christy Sheats’ great-grandfather “to protect the family.”

The sheriff’s office also revealed Monday that officers had been called out 14 times since 2012 to the Sheats’ home.

Some of the calls were related to alarm issues. Officials said due to the legal constraints by the country attorney, they couldn’t describe the other calls for service.

Sheriff's office spokeswoman Caitilin Espinosa had told People magazine that prior calls had involved a "mental crisis" related to Sheats.
