Colorado police have identified the people sought in security footage released after a Halloween party shooting that killed a University of Colorado Boulder student, as prosecutors consider additional charges.
On Thursday, Boulder Police Public Information Officer Dionne Waugh confirmed to Fox News Digital that “everyone in the photos and video we released” has now been identified.
The primary suspect, Omar Perez, 18, faces murder and related charges in the death of Luca Hanlon, 19, following a deadly confrontation at an off-campus Oct. 31 party in Boulders University Hill neighborhood.

After the arrest, detectives asked for the public’s help in identifying three other people seen in video and photos from that night, including two males, one wearing an “Art the Clown” shirt and another in a red hoodie, and a female witness.
Its unclear whether they will face charges.
“The investigation is ongoing. When and if there are additional arrests or charges, I will send out a news release,” Waugh said.
Shannon Carbone, the public information officer (PIO) for the Boulder County District Attorneys Office, told Fox News Digital that prosecutors “successfully argued in court Tuesday to have Perez held without bond.”
Perez’s preliminary hearing is scheduled for Feb. 10, 2027, according to the District Attorney’s Office.
The Colorado Public Defenders Office declined to comment on the case. The university did not immediately respond to requests for comment.

According to a Boulder police arrest affidavit, police first responded to a home off Marine Street around 9:58 p.m. on Halloween after receiving a noise complaint. Responding officers issued a nuisance-party citation, and hundreds of people left the gathering. Around 90 minutes later, at 11:28 p.m., officers returned after a call concerning gunshots fired.
Witnesses told authorities that Perez had been in the group of people that left, but he returned to the residence with six others. They were asked to leave, but Perez and his group allegedly became irate, leading to a scuffle in the living room and on the front porch. A witness said Perez appeared to be wearing a SWAT uniform and a “Purge” mask.
A resident at the home put Perez in a headlock, prompting Perez to allegedly pull out a gun and open fire, the affidavit stated.
One witness told police he heard Perez threaten, “Oh, I could shoot this place up.”

“I do not have any other updates on the second victim because of privacy. If that changes I will send out a news release,” Waugh told Fox News Digital.
