DENVER -- One person was killed in a stabbing at a downtown 7-Eleven store late Thursday night, the Denver Police Department said.
The stabbing happened just before midnight at 17th and Welton streets, one block from the 16th Street Mall.
Police have not confirmed if the stabbing took place inside or outside the convenience store or if it was part of a possible robbery attempt. Police say the suspect fled on foot.
Crime scene investigators went inside and outside of the store early Friday morning, taking pictures, collecting evidence and talking with witnesses.
Police are seeking assistance identifying the suspect pictured. He is described as a white man, roughly 5-foot-10 with a medium build.
He reportedly was wearing a dark-colored baseball cap with the Philadelphia Eagles logo.
He was also wearing a dark-colored coat with a hood, dark pants or jeans and dark colored athletic shoes with whit trim.
The victim was identified as 29-year-old Derek Sorenson. Police said Sorenson was the 7-Eleven store clerk working at the time of the attack.
He was taken to Denver Health Medical Center where he was pronounced dead. An autopsy was completed and it was determined the cause of death was from a sharp force injury.
Welton Street was closed between 17th and 18th streets for the investigation. It reopened about 6:45 a.m.
Anyone with information is asked to call 911.
