PLYMOUTH (CBS) — Two people are expected to appear in court Thursday to face charges related to the kidnapping of two nine-year-old girls from Plymouth.

Craig Beaudoin, 38, and Chareese Ford, 35, will be arraigned in a Lewiston, Maine courtroom. They each face two counts of kidnapping, two counts of assault and battery on a child, and conspiracy to kidnap after two fourth-grade sisters went missing on Wednesday night.

Ford, the girls’ mother, lives with her boyfriend, Beaudoion, in Lewiston, Maine while the girls’ father has full custody of them in Plymouth.

Local police found the girls, unharmed, with Beaudoin and Ford at their Maine home around 9:20 p.m. Wednesday. Police were able to unite the girls with their father early Thursday morning.

According to officials, Beaudoin forcibly took the girls from a store near their bus stop shorty after they were dropped off around 4 p.m.

Plymouth Police Chief Michael Botieri said police believe Beaudoin “had been watching the children at least for the day and we think maybe other days, preparing to do this, so there was some type of a preparation.”

“I think they just took advantage of the opportunity that the children weren’t picked up right away and (the children) ran into the store to use the bathroom,” Botieri said. “He followed them in, they had been following them and as soon the kids came out, they took the opportunity to abduct them.”

The girls’ father notified police that they were missing.
