Charles Buck Hanna, 63, was found shot to death inside his Walker Avenue home on October 7, 2010, after family members went to check on him when he could not be reached. Investigators determined the killing was tied to robbery: Hanna kept a large, valuable collection of firearms and about 27 guns were missing. The perpetrators removed a massive, heavy gun safe from the bedroom through the hallway — a task believed to require multiple people or specialized equipment. Two of the stolen weapons were later recovered but could not be linked to those who took them.

In the weeks before his death Hanna had told family he felt uneasy and had shown his collection to others; police say he likely knew his killers. The Indianapolis Metropolitan Police Department continues to list the homicide as unsolved and asks anyone with information about the missing firearms or the events around that October day to come forward.
