CROWLEY, Texas >> Officers responding to a report of a suicide attempt found four people dead inside a North Texas home Sunday afternoon, police said.

Crowley Police Chief Luis Soler said in a news conference Sunday night that a 9-year-old who was inside the home called a relative and told her that a man there was injured after attempting to kill himself. The woman then called 911, Soler said.

When police arrived at the home about four minutes after her call, around 4:15 p.m., they found two women, a man and a female child dead, according to Soler.

Officers also found the 9-year-old caller at the scene, apparently uninjured, Soler said. That child was in protective custody and was being interviewed.

Soler would not describe the nature of the victims’ injuries, saying only that the bodies had “obvious signs of trauma.”

“We don’t know exactly what happened out there,” he said, adding that the medical examiner’s office had not yet determined the victims’ identities or causes of death.

The four appeared to be “a family unit,” but it was not immediately clear exactly how they were related, he said.

Soler said that officers found no indication of a forced entry and that the initial investigation suggests it was an isolated incident. He said it was too early to call the incident a murder-suicide and said authorities would probably be at the scene all night.

The deaths will have “a huge impact in this tight-knit community,” the chief said. Crowley, a city of about 13,000, according to its website, is about 15 miles south of Fort Worth.
