Cheyenne Police Chief Brian Kozak says his department is hoping to have some new information to work with soon in the investigation of a double homicide that happened on July 20, 2015.

The chief says he expects to have results of DNA testing related to the case back next month, and says the investigation is "very strong and moving forward."

The shooting at the Coin Shop on West Lincolnway in Cheyenne claimed the life of the shop's owner, 67-year-old Dwight Brockman, and 76-year-old George Manley, who was a frequent customer.

The double homicide happened during Cheyenne Frontier Days, when the city is flooded with vast numbers of visitors, including a great many people not known in Cheyenne.

Kozak says the evaluation of forensic evidence in the case has been hampered by state budget cuts that have forced the department to send evidence that would have been evaluated at the Wyoming Crime Lab to Colorado. Those labs are extremely busy, including working on in-state cases there.

Police are hoping the DNA test results will shed new light on the case when they become available. Kozak has said previously that police have investigated hundreds of tips during their investigation as well as 230 pieces of evidence.

He has also said police have identified "several suspects" in their investigation. The killer has been described as a Hispanic male, standing around 5-feet and 7-inches tall.

Police believe he as wearing a dark shirt at the time of the killing. A sketch of the suspect is shown above this article.
