Police are saying that a tragic shooting in Denver today which left one adult and two children dead may have been a murder-suicide committed by a mother.

While details are still coming in, it has been reported that the children were under the age of ten. A third child, believed to be two years old, was rushed to surgery. The child’s father allegedly spoke to 911 operators and was hysterical while relaying the incident.

Officers are still investigating the events that led up to the shooting after responding early this morning. One witness–a neighbor–said he heard a gunshot around five a.m. before a vehicle sped down the street, but investigators say they don’t believe an outside party is involved.

“It appears to be an isolated incident. We are talking to people, we are now talking to witnesses, but we have no indication that there is a shooter out there on the loose in Denver,” Lt. Matt Murray said.

Detectives are sympathetic to a neighborhood in shock and ask for patience while they sort out the details.

“I would ask that we all keep those involved — those that are going to be faced with this horrible tragedy — in our thoughts,” Denver Police Chief Robert White said.
