Editor's Note: This article has been updated with new information from the Boston Police

New surveillance photos connected to the death of 22-year-old Stephen Perez outside a downtown nightclub April 28 have been released by police.

Perez, an Army sniper who saw time in both Iraq and Afghanistan, was a student at Bunker Hill Community College and the president of the BHCC Veterans' Student Club.

According to a WHDH Boston report, Perez had just returned from a tour overseas when he was killed outside a Theater District nightclub on April 28.

Investigators released the attached surveillance video over the weekend, and now say they have determined where those individuals were that evening.

Homicide investigators have determined that the individuals captured on released surveillance images were seen earlier in the evening attending a birthday celebration at the Caprice Lounge and Underbar. Detectives continue to seek the identity of the individuals seen coming down the parking lot ramp. Detectives would also like to speak with any witnesses who may have seen these individuals at the Caprice Lounge and Underbar earlier in the evening.

At about 1:57 a.m. on April 28, officers from District A-1 responded to a report of a person shot at 290 Tremont St. Upon arrival, police located Perez outside, suffering from what appeared to be a gunshot wound. He was transported to Tufts Medical Center with life threatening injuries, where he was subsequently pronounced dead.

Additionally, police are seeking witness photos or video taken in the vicinity of 290 Tremont St. and Stuart Street—either on the street or inside a nearby establishment—that night. Anyone with any information on the shooting should contact Sergeant Detective Marc Sullivan at SullivanMa.bpd@ci.boston.ma.us or call the Homicide Unit at 617-343-4470.
