A Texas woman found the dead bodies of her three children when she walked inside her Stafford home on Tuesday.

According to KHOU, authorities said that they are investigating the shooting deaths of 23-year-old Faheem Ahmed Mughal, 18-year-old Fahad Mughal and 15-year-old Rebecca Mughal as an apparent murder-suicide.

Police said that the hysterical victim’s mother dialed 911 just before 2 p.m. and screamed that her “baby was dead.”

The Houston Chronicle reported that the distraught mother said that she came home to the horrific scene and found two of her four children dead. However, when police searched the house further they discovered the body of another one of her children.

The unidentified woman’s fourth child, a female in her mid-20s, was not home at the time of the slayings.

It is unclear at this time who pulled the trigger, but a pistol was found next to the bodies of one of the two brothers.

The parents of the siblings have not yet been interviewed by investigators.
