WATERVILLE – Three teenagers were involved in the recent stabbing of a taxi driver, police said Friday.

The disclosure came after the arrests this week of the final two suspects.

Police made the first arrest a week ago, when a 14-year-old girl admitted that she had stabbed the cab driver twice in a botched robbery attempt. She refused to identify her accomplices.

Police Chief Joseph Massey said a second 14-year-old girl was arrested on Monday. The girl gave police information that helped them identify the other teenager who had been in the car, Massey said. The names of both girls were withheld by police because of their ages.

On Friday, Michael A. Damron Jr., 18, was arrested at Waterville Senior High School, where he is a senior.

“They’re all friends,” Massey said. “They hung around together.”

All face felony charges of robbery and elevated aggravated assault.

“It’s kind of striking when we have a crime committed with that level of violence and 14-year-old females are involved,” Massey said.

Although the first girl admitted to the stabbing, police aren’t “100 percent sure” that’s true, Massey said.

“The first 14-year-old was very detailed in what she did, with so much detail that it really led us to believe she was the stabber,” he said, “but there are now conflicting stories about who actually did the stabbing. The stories differ somewhat between the three of them as to who actually did what.”

Police said the driver, who works for G’s Taxi, picked up three people in a parking lot beside 69 Water St. late on Dec. 1 and drove them to Willow Street, a short, dead-end street near College Avenue/Route 201.

The driver told police that one of the passengers grabbed him from behind around the throat and he was stabbed twice. The driver honked his car’s horn, sending the three people running from the cab, then drove to the Cumberland Farms convenience store on College Avenue to report the stabbing at 11:27 p.m.

The driver, who was released from MaineGeneral Medical Center’s Thayer Campus the next day, initially told police that he thought the passengers were two dark-skinned males and a young female. Police have not named the driver.

Police said they received a tip that led them to identify the first 14-year-old girl, who had no stable place to live and had two outstanding warrants for her arrest. The second girl also did not have a stable home, said Massey.

The girls were staying in separate apartments in the city. They are now being held in the Mount View Youth Center, a juvenile detention facility in Charleston.

Damron was taken to the Kennebec County Jail in Augusta and held on $100,000 cash bail.

Massey said police did not have any further insight into the failed robbery, which the first 14-year-old girl said was her idea.
