Denver police are asking for the public’s help in finding a former funeral home owner who they say kept a woman’s body in a hearse for two years and kept the cremated remains of at least 30 people.

In announcing an arrest warrant last Friday, police said Miles Harford was cooperating with investigators. However, on Thursday they offered a $2,000 Crimestoppers award for information leading to his arrest because he hasn’t turned himself in to authorities and they can’t find him.

A warrant lists potential charges of abuse of a corpse, forgery of the death certificate and theft of the money paid for the woman’s cremation. Other charges are possible as the investigation continues, Denver District Attorney Beth McCann said last week.
