Police allege a Maryland man was driving while under the influence when he caused a four-car crash that killed an elderly man in November 2014.

Trent Loye Holderman, 32, of Arnold, Maryland, is charged with homicide by vehicle, aggravated assault by vehicle, DUI, three counts of reckless endangerment and several traffic-related summary offenses related to the November 2014 crash, according to charging documents filed Dec. 21, 2015.

Shortly before noon on Nov. 8, 2014, emergency personnel were called to Exit 19 on Interstate 83 for reports of a crash, according to documents. Holderman's Ford F-150 had crashed into a Cadillac DTS, also damaging two other vehicles, near that exit, which is for Market Street in Springettsbury Township, according to police.

The crash: State police spokesman Trooper Rob Hicks at the time said Holderman's car crashed into the other cars as they were waiting in the congestion at the off-ramp.

"Traffic was stopped. It was backed up on that exit ramp," Hicks said at the time. "For some unknown reason, that fourth car didn't notice traffic stopping ... and rear-ended that first car. It caused a chain reaction."

Carrol Shaffer, 86, of Parkton, Maryland, had been driving the Cadillac; he died at Memorial Hospital shortly after the crash. His daughter told police she and her parents had been going to lunch and were waiting in traffic in the exit lane when a vehicle crashed into them from behind, documents state.

Police say they could smell a faint odor of alcohol on Holderman, and that his eyes were bloodshot and glassy. He failed a field sobriety test at the scene, they said. A blood sample was taken shortly after the crash; tests later would show alcohol, Xanax and THC in his system, documents state.

Holderman told police he'd been drinking the night before, but had stopped at 3 a.m., nine hours before the crash, according to documents.

He also told police the Cadillac wasn't totally in the exit lane, and was partially blocking the lane next to it, documents state.

Crash reconstruction indicated Holderman had been speeding, going 76 mph in a 55 mph zone, and that the Cadillac had been fully in the exit lane, as it was supposed to be, police say.

The York County Coroner's Office said Shaffer died of blunt trauma to the torso, and ruled the death an accident.

Shaffer's wife, who had been in the front passenger seat of the Cadillac, suffered a punctured lung, broken ribs and a back injury that required months of physical therapy, Shaffer's daughter told police.

Justin McShane, who's listed as Holderman's attorney, did not respond to a message seeking comment.

According to online court records, Holderman remains in York County Prison on $25,000 bail, but prison records say he hasn't been there.
