ADAMS TWP - A Middlesex Township man was drunk when he crashed his car early Christmas Eve, killing himself and a passenger and injuring two others in the same vehicle, according to an autopsy report.

Joseph Staab, 25, was more than three times over the legal blood-alcohol limit when his Pontiac Grand Am slammed through a guardrail and crashed along Mars-Evans City Road.

Staab and Cory Lee Greiner, 23, of Middlesex Township died in the 2:27 a.m. Dec. 24 crash. Both men were thrown out of the car and were pronounced dead at the scene.

Shawn Andrew Green, 24, of Valencia and Joel Flores-Jones, 23, of Mars were treated at Pittsburgh hospitals for injuries in the crash, and later released.

Adams Township police said Staab was speeding in the car when it traveled off the road and became airborne.

Toxicology results recently released by the Butler County Coroner's office showed Staab's blood-alcohol level was 0.249 percent, following a post-mortem examination.

A BAC level of 0.08 and above is considered intoxicated for drivers, under state law.

Greiner's BAC was 0.237 percent, according to his autopsy.

Police suspect the four men had been drinking at a Cranberry Township bar the night of the crash. They were traveling to Staab's house when the car crashed.

No other motorists witnessed the wreck.

Officers smelled alcohol coming from the four men when they answered the accident call, said Adams Township police Chief Bill Westerman.

He said police still want to talk to Green and Flores-Jones about the crash.

"We've been trying to speak with them," he said. "We'd like to know what was going on before this happened."

Police are still awaiting a state police accident reconstruction report that could determine the estimated speed of Staab's car.

Westerman said none of the occupants was wearing a seat belt.

Staab died of head and body injuries and Greiner died of body injuries, the coroner's office said.

Green suffered a concussion, cuts and bruises and Flores-Jones suffered a broken leg, police said.

"This just goes to show you that alcohol and speed don't mix," Westerman said. "How many cases like these do we have to see before people understand that?"
