He was rushed to Denver Health Medical Center for emergency medical treatment where he died a short time later.

Police say while reviewing surveillance footage it was discovered that an argument occurred between a man and the victim in the foyer of the building adjacent to the entrance for the 7-Eleven a few hours prior to the stabbing.

The argument was broken up by security officers from Securitas.

Surveillance video also shows the attack in front of the 7-Eleven and the suspect running away from the scene.

In both instances, the suspect was wearing a baseball hat with the “Eagles” logo and had similar physical features.

A man with the same description was also spotted at a Jack in the Box in Commerce City, approached a 17-year-old worker and sent her a friend request on social media.

The social media request was from a man named Luis A. Perez with the vanity name “louietray.”

Police believe the same man was seen on surveillance video at US Bankruptcy Court to file a bankruptcy on the same day of the stabbing and gave the name Luis Antonio Perez.
