LAMOINE – Three male teenagers being held in jail in connection with multiple weekend break-ins in Mariaville and Otis may face additional charges in connection with Lamoine break-ins, an officer with the Hancock County Sheriff’s Department said Tuesday.

The charges will be filed pending completion of a joint investigation of the burglaries with the Maine State Police, Lt. Tim Cote said. He declined to say how long the investigation may take or when the additional charges would be filed.

Hancock County sheriff’s deputies were in Lamoine on Tuesday afternoon investigating reported break-ins at three homes and at a tollbooth in Lamoine State Park.

Michael Tibbetts, 18, of Lamoine, Bryan Lennon, 18, of Ellsworth, and a 17-year-old male juvenile from Otis admitted to police that they kicked in the door to the tollbooth and set off a fire extinguisher inside, Deputy Corey Bagley said Tuesday.

According to Hancock County Sheriff’s Deputy Loren Clarke, a computer and checkbook were reported missing Monday from a Fox Run home in Lamoine. Several steak knives also were left with their blades sticking into the kitchen counter of the residence. A second home on Fox Run and a garage on Kitts Crossing also were broken into, deputies said.

Tibbetts, Lennon and the juvenile were arrested Monday by state police after they approached Trooper Alden Bustard at an Otis gravel pit and reported that they had been held at gunpoint, according to state police. An Otis man who suspected the trio broke into his home detained them with a gun Monday but let them go after failing to find any of his possessions with them, police said.

The teenagers approached Bustard while riding in one of the five vehicles they are accused of stealing during the spree, according to police. Bustard was investigating some of the reported burglaries and, after talking to the trio, connected them to the break-ins, police said.

Besides the Lamoine burglaries, the teenagers are suspected of kicking their way into a total of nine homes in Mariaville and Otis. Reported stolen from the homes in Mariaville and Otis are two guns, liquor, flashlights and a laptop computer, police said. One of the guns was recovered Monday in one of the stolen vehicles, four of which have since been found, police said.

The teenagers were still in jail Tuesday on charges connected to three burglaries in Otis and one in Mariaville.
