Roxann Martinez, 31, was found shot to death at the intersection of East Kenyon Drive and South Wabash Street in Denver on February 25, 2021. The Denver medical examiner ruled the death a homicide from a gunshot wound.

Martinez had been expected to testify for the prosecution in the 2013 murder case of Kelsie Schelling, which raised early public speculation that her killing was meant to silence her. The Denver Police Department said it had no evidence linking her death to that trial and did not believe the cases were connected.

Investigation attention turned to her ex-boyfriend, 29-year-old Emmanuel Chandler, who was described as a Black male, 6 feet 1 inch and 180 pounds. Chandler turned himself in and was held for investigation of first-degree murder. Prosecutors presented evidence at trial that Chandler shot Martinez, dumped her body at the roadside and attempted to use bleach to cover up the crime; a Denver jury found him guilty of one count of first-degree murder after about six hours of deliberation.

Did anyone in the Denver area know Roxann, her routines, or have information that could help explain what led to that February night?
