Loganville Fire Chief Rodney Miller was killed early Saturday morning while directing traffic on Interstate 83 near the Glen Rock exit (Exit 8).

Miller, 45, of the Seven Valleys area, was directing traffic on Interstate 83 southbound when he was struck by a vehicle about 12:30 a.m., according to the York County Coroner's Office.

Miller was rushed to York Hospital, where he was pronounced dead at the scene, Deputy Coroner Jeffri Goodfellow said.

Police have arrested Matthew Scott Diehl, 32, of Shrewsbury, and charged him with homicide by vehicle while driving under the influence and other violations.

Authorities earlier had closed a stretch of the interstate to clear the way for a medevac helicopter, which was approaching the scene of a prior accident, according to a news release.

Miller had parked his vehicle in the southbound lanes at Exit 8 and was diverting traffic off of the highway. He had activated his emergency lights, state police said.

Diehl was traveling south on I-83 in the left lane. He switched to the right lane to move around Miller's vehicle and struck Miller, police said. He continued south until he was forced to stop because of vehicles caught in the backlog of the earlier crash, according to police.

An autopsy was to be performed Saturday, Goodfellow said.

State police are investigating.
