SPOKANE, Wash. -

Gail Gerlach entered a not guilty plea on a first degree manslaughter charge for the killing of Brandon Kaluza-Graham on March 25.

Gerlach was making his first appearance on the charge stemming from the incident, where Kaluza-Graham attempted to steal Gerlach's SUV, which had been idling in his driveway. Gerlach fired a single shot at the SUV as Kaluza-Graham was driving away from his home.

Kaluza-Graham was hit in the head and died nearly instantly.

Following the brief appearance, Gerlach was taken to the Spokane County Jail where he was to be booked, fingerprinted and subsequently released.

Before he was taken to the jail, Gerlach spoke publicly for the first time, addressing the number of supporters who came to the courthouse in a show of solidarity with him.

"I think they're good people and they mean well and we'll just take it from here and see what happens. I appreciate anyone's support but that's not why we're here," he said.

Members of Brandon Kaluza-Graham's family were also on hand for the court hearing.
