BUTLER TWP — A 21st birthday celebration didn't end well for a Butler man or his mother.

Both were arrested for driving drunk — in the same car.

Andrew J. Henry, 21, and Sabrina M. Henry, 45, of Butler are both charged with driving under the influence and careless driving. Sabrina Henry also was cited for driving at an unsafe speed.

Butler Township police came upon mother and son shortly after 8 p.m. Oct. 2 after a resident on Bean Street called to report two intoxicated people on his property.

At the home, police said, Sabrina had driven her car on decorative rocks along the driveway. She apparently was unable to get the vehicle off the rocks.

That's when Andrew tried to help out. He switched places with his mother, police said, and backed up the car — right into the resident's truck parked on the other side of Bean Street.

Both Henrys smelled of alcohol. Andrew told officers that he and mom were “out celebrating his 21st birthday,” according to a police affidavit.

He admitted having consumed a lot of alcohol, police said. He also told officers that his mother was driving when they left the Days Inn bar on Route 8 south in the township.

Sabrina later acknowledged that she made a wrong turn leaving the bar, police said. She said she turned left onto Bean Street, according to court documents, thinking it was Route 8.

She got the car caught up on the decorative rocks, her son recounted to officers.

“(Andrew) stated that he then tried backing out and rear ended the truck,” according to court documents.

Both defendants, following field sobriety testing, were taken to Butler Memorial Hospital for a blood test. Results showed Sabrina's blood-alcohol level was 0.215 percent; Andrew's was 0.147 percent.

A level of 0.08 percent is considered intoxicated under state law.

Preliminary hearings for the two are set Dec. 20.
