The Dillsburg man driving a car that crashed Easter morning, killing him, his sister and another man, was drunk, the York County coroner's office said Friday.

John Michael Howard, 21, of Dillsburg, had a blood alcohol content of 0.131 percent at the time of the crash, the coroner's office said.

In Pennsylvania, a driver may be charged with DUI with a BAC of 0.08 percent.

Howard, his sister, Amy Howard, 18, and Christopher Jones, 21, all of Dillsburg, were killed when John Howard lost control of the car, a 1998 Ford Escort, and ran into a bridge abutment on Capitol Hill Road in Franklin Twp. at 12:10 a.m. April 8, according to Northern York Regional Police.

A 15-year-old boy in the car sustained serious injuries and is recovering, police said.

Police said speed also was a factor in the crash.

The toxicology results were returned Thursday.
