Oscar Martinez, 42, was fatally shot on December 6, 2016, in the Security-Widefield area of Colorado Springs. The shooting occurred near an apartment complex on or around the 500 block of Security Boulevard; neighbors reported waking to police lights and a taped-off courtyard in the predawn hours. Residents said Martinez had been camping outside the building and appeared to have been staying close to the complex in the days before the killing, a detail that underscores how he was living at the margins and was shot where he slept just steps from warmed hallways and stairwells.

Detectives opened a homicide investigation, but authorities did not announce an arrest in the immediate aftermath, and memorial listings record Martinez as lost to gun violence on that date with no follow-on notices of a suspect or court proceedings. Few details beyond his name, age, location, and the scene of the shooting have been published. If anyone knew Oscar, saw activity around the 500 block of Security Boulevard in early December 2016, or has information that could help the investigation, please share what is known.
