An official with the Cheyenne Police Department says investigators are working their way through a mountain of evidence as they try to solve a double homicide that occurred at a Cheyenne Business last Summer.

Lt. Terry Bell says so far police have executed 18 search warrants, seized over 200 pieces of evidence, investigated 103 tips and currently have DNA evidence being evaluated in both Colorado and Wyoming laboratories.

Bell says police now must tie together the evidence and corroborate the results of the investigation to ''bring this to conclusion." The July 20 shooting at The Coin Shop on West Lincolnway claimed the life of 67-year-old Dwight Brockman and 76-year-old George Manley, both of Cheyenne.

Brockman owned the business while Manley was a frequent customer.
