Denison Police have opened a homicide investigation after the body of a man was found inside a business late Tuesday night.

Lt. Mike Eppler said Robert Allen, 55, was found dead inside Allen Plumbing off Eisenhower Parkway.

“It was at about 10:30 p.m. last night that we got the call of a possible shooting,” Eppler said. “There was one deceased person there, a Robert Allen. He’s part of the family that owns the business.”

Eppler said the department would await the results of an autopsy before commenting on Allen’s cause of death. Citing the ongoing work of investigators, who remained at the business Wednesday morning, Eppler also declined to comment on the crime scene.

“We’re following up on leads but we don’t have any firm suspects or anything like that right now,” Eppler said.

The Denison Police lieutenant said anyone with information relevant to the investigation should contact the department immediately.

“We want them to know what’s going on and that if they see anything suspicious, they should please give us a call,” Eppler said.
