A Massillon Perry Schools teacher is in critical condition after a rock thrown from a highway overpass struck the car in which she was a passenger.

Sharon Budd, 52, of Lake Township, is in critical condition at Geisinger Medical Center in Danville, Pa., according to the Akron Beacon Journal. Four teenagers have been charged in the incident, accused of dropping a 7- to 8-pound rock from an overpass on Interstate 80.

The Sunbury, Pa., Daily Item reports Budd, her husband Randy and their daughter Kaylee were traveling eastbound on I-80 on a trip to New York City when a large rock thrown from an overpass struck their vehicle at 11:56 p.m. Thursday.

The rock reportedly smashed throw the car's front windshield and hit Sharon Budd, who was in the passenger seat, in the face. Kaylee Budd was driving the car, according to Pennlive.com.

Lindsay Bannister, a family friend, told the Daily Item that Budd lost an eye and had to have parts of her skull removed to allow the brain to swell for a risky procedure. If Budd survives, she will need multiple facial reconstructive surgeries, Bannister told the Daily Item.

The Beacon Journal reports Budd was to undergo a day-long surgery.

Two teens, Brett Lahr, 18, and Dylan Lahr, 17, of New Columbia, Pa., were arrested late Friday night in the incident and face identical felony charges of aggravated assault and conspiracy, as well as seven misdemeanors. Dylan Lahr has been charged as an adult, according to the Daily Item.

In addition, two more juveniles could face charges as adults, the Daily Item reports.

"It's a heinous crime. What they did is beyond absurd and ridiculous. They should be charged to fullest extent of the law," said Sgt. Frederick Dyroff of the Milton State Police Barracks said Monday.

Randy, her husband of 31 years, and their children Luke, 29, James, 24, Joey, 22, and Kaylee, 19, have been at the hospital since the incident, according to the Daily Item. Luke Budd, a National Guardsman, was specially brought in Friday and was scheduled to be deployed for his second tour in Afghanistan later this month.

Sharon Budd had just finished speaking with Luke on the phone moments before the incident, Randy Budd told the Beacon Journal.

"My son's picture was the last thing she saw," Randy Budd said. "She was crying, but it was a good cry."

Sharon Budd is a language arts teacher in Perry and a breast cancer survivor, her husband said.

"She's a tough lady," Randy Budd said. "She's a fighter."
