'Who killed Mar-Shun?': DPD asking public for information on homicide case



DENVER (KDVR) — The Denver Police Department is asking the public for “assistance” in solving a 2020 homicide case.

Saturday marks five years since Mar-Shun Cox, 29, was shot and killed outside of an apartment complex in the 1400 block of East 31st Ave. on Sept. 6, 2020.

“Your Denver Police Department needs assistance solving this homicide case,” said DPD in a post to Facebook on Saturday.

A detective on the case, Mark Crider, told FOX31 in April 2023 that police believed Cox had been confronted in the parking lot by “unknown people.” Cox was then shot in the parking lot while trying to run from the area.

The detective previously noted that the deadly shooting was believed to be targeted and that two or more suspects were involved in the incident. 

“We’ve run down our leads, our forensics evidence has been tested and we’re still looking for leads to find who’s responsible for killing Mar-Shun,” said Crider. 

Investigators believed as of 2023 that multiple witnesses were outside in the parking lot and on balconies at the time of the incident. However, the detective had noted that there were no credible leads.

In 2023, Cox’s mother, Passion Hillsmon, spoke to FOX31 about her son and asked any witnesses to come forward. 

“Somebody out there knows what happened to my son, and I just beg them, please, just come forward. My son’s life mattered. He mattered to this family. He was important,” said Hillsmon. 

Anyone with information is asked to call Metro Denver Crime Stoppers at 720-913-STOP or submit a tip online.
