Authorities hope an increase in the reward for information in the slaying of a Crystal Springs convenience store clerk will lead to the arrest of a suspect.

Police say various donors are offering $31,000 for credible information.

Twenty-nine-year-year William Donahoe was shot and killed March 6 during a robbery.

Police say the shooter was described as a slender male, about 5 feet 10 inches, wearing a black baseball cap, a black and white, button-down shirt, blue jeans and a black bandanna.

Police say the majority of the reward money — $20,000 — was contributed by an anonymous business owner. That was added to $10,000 being offered by the owner of the store and $1,000 from CrimeStoppers.
