COMMERCE CITY, CO (Thursday, Feb. 19, 2026)The Adams County Sheriff’s Office continues to seek information regarding the tragic homicide of Alaina “Evan” Martinez, which occurred at approximately 3:00 a.m. on October 15, 2022, in the 900 block of Dakin Street in unincorporated Adams County.

“Behind every cold case is a family still waiting for answers. We owe it to this victim and their loved ones to pursue every lead, which is why we’re asking for the public’s help,” said Adams County Sheriff Gene Claps. “We want the public to know that no piece of information is too small and could be what we need to help solve this case.”

Detectives continue to actively investigate the case and follow up on tips as they are received. We remain hopeful that our community will come forward with information that will help us secure justice for Alaina and the other victims.
