Police arrest man in deadly stabbing of Denver 7-Eleven clerk

DENVER – Police have arrested a man suspected of stabbing a 7-Eleven clerk to death last Thursday night.

Luis Perez, 33, is being held for investigation on first-degree murder charges in the death of 29-year-old Derek Sorenson.

According to an affidavit for Perez’s arrest, Sorenson, who was a clerk at the store located near 17th and Welton, had been in an argument earlier in the night with Perez.

Upon reviewing surveillance footage, police discovered that Perez came back to the store and stabbed Sorenson several times before fleeing the scene, they wrote in the affidavit. Sorenson went back into the store and collapsed. He died after being transported to an area hospital.

A tipster called police after they put out a surveillance image of the suspect in the case and identified him as Perez.

Further investigation revealed that Perez had come to U.S. Bankruptcy Court in Denver the day of the stabbing to file a claim. A detective at the court identified the man as the same person seen in the surveillance images.

Another person identified Perez as the person seen in the surveillance video as well, and said Perez had told them that the 7-Eleven clerk had accused him of stealing.

And according to the affidavit, yet another person interviewed by police, who had come into contact with Perez the night of the murder, said Perez had said the clerk had “messed with the wrong person” and that he would “be back later.”

Perez’s affidavit carries a no-bond hold request.
