The day after Christmas 2013, Denver police responded to a reported burglary at a Trenton Street home and discovered two men shot to death inside: 39-year-old Francisco Gutierrez, a Hispanic male, and 37-year-old Alexander Tower. Gutierrez had sustained multiple gunshot wounds; both deaths were treated as a double homicide. Authorities established the men had been last seen together in the early morning hours of December 22 at a downtown nightclub and canvassed the neighborhood while seeking public tips in the days after the bodies were found on December 26.

By early 2014 investigators reported no significant developments and no arrests, and the case later appeared on the city’s list of unsolved homicides. Few public details about a possible motive or suspects have been released. If anyone who knew Francisco, Alexander, or their movements around December 22–26, 2013 has information, please contact the Denver Police Department.
