Clint Burtts was 52 when a violent assault on September 18, 2013, near Speer Boulevard and Stout Street in Denver left him hospitalized with serious injuries. He survived for nearly seven months but died on April 10, 2014, from complications of those injuries, at which point the investigation was reclassified as a homicide.

Investigators later circulated a description of a transient man known as Michael, nicknamed Wolf, who was often seen with a dog called Pork Chop and who frequented the area of Interstate 25 and Speer Boulevard. Metro Denver Crime Stoppers offered up to a $2,000 reward for information leading to an arrest, but no arrest has been announced and the Denver Police Department currently lists the case as cold.

If anyone has information about Michael Wolf, his dog Pork Chop, or sightings around I-25 and Speer Boulevard in 2013, please come forward to assist the investigation.
