(Hamilton)--Butler County Prosecutor Mike Gmoser was part of a press conference on Thursday to talk more about the dead gunmen responsible for shooting an officer on Saturday.

Gmoser says that 18-year old Brandon Keeler wanted to be killed by police when he went walking through the streets of Hamilton shooting an AK-47 and carrying a Glock handgun. Officer Chad Stafford responded and was hit in the head with a non-life threatening injury. Stafford returned fire and killed Keeler in the street.

Investigators say that Keeler may have been influenced by the video game "Grand Theft Auto".

Officer Stafford was cleared of any wrong doing by an investigation that included the Bureau of Alcohol, Tobacco and Firearms.
