AMERICAN FORK — Police are looking for three pregnant teens who they believe fled a residential group home after attacking the home's director Tuesday, and then stealing her car and credit cards.

"Three of the girls, two 15-year-olds and one 16-year-old, hit the director over the head with a frying pan and then they took some electrical cords and tied her up and put a sock in her mouth and taped her mouth," said American Fork Police Sgt. Shauna Greening.

The home, which provides a place to stay for struggling pregnant teens, had four teenage residents at the time of the incident. The teens accused of attacking the home's director also tied up a 17-year-old girl.

The three teens — who are from California, Texas and Illinois — then stole the director's purse, checkbook, credit cards, cell phone, video camera and a 2005 Dodge Caravan with Utah license plate number 128 VTX, according to police.

After the teens fled the small residential house, the director was able to free herself.

"The victim was able to break free and then she went up and untied the 17-year-old female and then they contacted the police," Greening said.

Police said they believe the girls have fled the state, but they will face a slew of charges when found, including "aggravated kidnapping, aggravated robbery, theft of a vehicle, criminal mischief and aggravated assault," Greening said.
