A SWAT team responded to the scene and made an emergency entry into the residence. Police found the suspect and the daughter dead from gunshot wounds.

The suspect and the woman rescued were married and living at the home with their two children, LVMPD homicide investigators determined. The couple had gotten involved in an altercation that turned violent when the man attempted to shoot the woman, police said. 

The teenage son intervened in the altercation before he and his mother escaped the house with nonlife-threatening gunshot wounds and placed a call for help, police said. The suspect then shot and killed his daughter before taking his own life, according to police.
