Heather Sue Pierce, a 33-year-old White woman, was found unresponsive in the 1800 block of Little Raven Street in Denver on April 22, 2011. She survived for two months after the discovery but died of her injuries on June 23, 2011. An autopsy found blunt force trauma was the cause of death, and the death was ruled a homicide.

The Denver Police Department investigated, canvassing the area for witnesses and evidence. No suspects were publicly identified and no arrests were announced, and the case later went cold. The homicide remains listed with the department’s cold case unit and law enforcement has continued to appeal for information.

Anyone who knew Heather, was in the Little Raven Street area on or around April 22, 2011, or has information that could help investigators is asked to come forward.
