Woman Killed Two Daughters In Husband Presence

In one Emergency call recordings, a woman is heard crying: "Please! Forgive me! Please! Don't shoot!"

According to Christy Sheats' Facebook page, she was a gun rights advocate and had posted comments about how much she loved her family.

The emergency call recordings have been released revealing the terror in a Texas home as a mother killed her two daughters in front of her husband.

Fort Bend County Sheriff's Office released tapes of 911 calls from the Houston-area house where 42-year-old Christy Sheats fatally shot her two daughters on Friday afternoon.

After a scream, she cries: "Please! I'm sorry! Please! Don't point that gun at her!"

The gunwoman's husband, Jason Sheats who was unharmed in the attack is heard saying: "I promise you, whatever you want."

The call is then disconnected.

In another call, a neighbour describes 17-year-old Madison Sheats and 22-year-old Taylor Sheats lying fatally wounded in the street outside their home.

The neighbour describes Christy Sheats kneeling over her eldest daughter and shooting her dead.

In a news conference on Wednesday, Sheriff Troy Nehls told reporters that Christy Sheats had a history of depression and suicide attempts and was about to divorce her husband.

"We asked Mr Sheats for a motive in his own words," Sheriff Nehls said. "He stated that he felt Christy wanted him to suffer." 

Sheriff Nehls said Christy Sheats had "ample time and opportunity to shoot and kill Mr Sheats in the home, but she chose not to".

He added: "Mr Sheats stated that Christy knew how much he loved Taylor and Madison and how much they loved him.

"By killing his children, Mr Sheats will have to live the rest of his life with this horrible memory."

The sheriff said the marriage had been in a "downward spiral" since 2012 when Christy Sheats' grandfather, who raised her, died. 

The shootings happened on Mr Sheats' birthday and on the week the couple's oldest daughter was to get married. 

Sheriff Nehls said the final straw came when Christy Sheats had tried to ground Taylor after a quarrel and prevent her from seeing her fiancé.

Mr Sheats had told his wife she could not ground their 22-year-old daughter just days before her own wedding.

A family friend said the mother had inherited the gun from her great-grandfather.

An officer killed Christy Sheats after she refused orders to drop her gun.

Sheriff Nehls said the unidentified officer has had a "difficult time" since the shooting.
