Authorities are growing increasingly concerned about the disappearance of two 14-year-old girls, who are students at Bonny Eagle High School.

Friends and family have not seen or heard from the girls, who are believed to be together, in nearly three days.

Earlier today, Buxton Police Chief Michael S. Grovo issued a press release, calling on the public for any help they might be able to provide in locating the missing teenagers.

Grovo said it appears that Rachel Ann Fuller of Buxton and Dominique Lee Sproul of Limington, who are freshmen at Bonny Eagle, ran away sometime after classes ended Tuesday. They did not have access to a motor vehicle.

“The investigation has led us to believe that they ran away,” Grovo said. “But my concern is their young age as well as their welfare and safety.”

Grovo said he may contact the National Center for Missing and Exploited Children for assistance unless investigators get a more substantial lead on the girls’ whereabouts.

The investigation is a joint effort between the Buxton Police Department and the York County Sheriff’s Department.

“We feel the girls are somewhere in the Portland area based on the information that has turned up during our investigation,” said Sgt. Ron Lord of the Sheriff’s Department. “The parents are really concerned for their children.”

Portland Police went to the OccupyMaine encampment in Lincoln Park this afternoon and tonight to check on a tip that the girls had been seen there. But Lt. Robert Ridge said the police walk-throughs did not produce any substantial leads.

Andrea Fuller, a single mother, said she last spoke with her daughter around 2:40 p.m. Tuesday.

“She called me (on her cellphone) when she got home from school and indicated she wanted to go out with friends,” Fuller said.

Fuller, who had made plans to take her daughter to a Portland Pirates’ hockey game that night, told her to do her chores and to wait at home until she arrived.

Three weeks ago, Fuller said, she was forced to take disciplinary measures against Rachel by taking away her cellphone privileges. Rachel broke up with her boyfriend, a student at Scarborough High School, about one week ago.

“Freshman year has been tough,” said Fuller, who lives alone with her daughter.

Since her disappearance, Fuller has been using her Facebook page – Andrea Temm Fuller – as a means of communicating with people who knew her daughter or who might know where she is.

Fuller is described as being 5 feet 4 inches tall, weighing 150 pounds, with brown shoulder-length hair, blue eyes and fair skin. She has nine ear piercings.

“Rachel hasn’t called or texted me. She has never done anything like this before,” Fuller said.

George Sproul, who is also a single parent, said his daughter, Dominique, has run away from home before but never for as long as this most recent incident.

“I’m beside myself,” he said. “I’ve been calling everyone I can think of but no one has seen or heard from them.”

Rachel Fuller had posted a message on another person’s Facebook page about the girls wanting to go to Massachusetts to visit Dominque’s mother, Deborah Desilva, but Sproul said police have confirmed that she is not there.

He last saw his daughter when she got on the school bus at 6:35 a.m. Tuesday.

Sproul is 5 feet 6 inches tall, weighs 140 pounds and has red hair and hazel eyes.

Anyone with information about Fuller or Sproul should contact the Buxton Police Department at 929-6612 or the York County Sheriff’s Department at 324-3644.
