Dispatchers received a call at around 8:28 a.m. about a self-inflicted gunshot victim at a Ponder home and, while police were en route, they were notified of multiple other victims, the Denton County Sheriff's Office said.
News of the murder-suicide shocked residents of the suburban town with a population of less than 1,400 people.

Neighbor Natalie Carr, who lives across the street from where the shooting occurred, said three children lived in the home. Ponder ISD said it had no students or staff listed at the home's address nor any absences that would raise alarms. That one surviving victim was transported to Medical City Denton, but the individual's condition is still not known at this time.
