Officer Simon Drobik said police were called to the Circle K on at Lomas and Eubank around 7 p.m. Sunday.
“Witnesses said two males got into some type of disturbance that spilled out of Circle K into the westbound area of Lomas,” Drobik said.
When police arrived, they found one man dead. The cause of his death has not been determined, Drobik said.
Witnesses offered descriptions of the second man, and police canvassing the area found him near Babies “R” Us, about a half a mile from the gas station.
“We do have the offender in custody, we believe,” Drobik said.
That person, who was injured, was taken to a local hospital for treatment. Drobik said it was not clear whether the man’s wounds were self-inflicted or sustained in the fight.
Neither of the men have been identified.
Drobik said westbound Lomas will remain closed as officers conduct an investigation, which could last through the morning. He said detectives have “numerous witnesses” to interview.
