BRATTLEBORO -- A 20-year-old Brattleboro man has landed in jail for three to nine years for assaults that included lighting a man’s hair on fire and kicking a pregnant woman.

The prison time was imposed this week after Devon Longueil pleaded guilty to 16 charges -- including six assault counts and two counts of obstructing justice -- in Windham Superior Court Criminal Division.

The earliest case involved in the plea deal dates to May 6, 2010, when Longueil -- then just 16 -- was accused of assault on Flat Street in Brattleboro.

A man told police that, in front of the Transportation Center, Longueil "came up behind him and lit his hair on fire with a lighter."

The victim "was able to put it out quickly, as he had a friend with him," police wrote in an affidavit. The victim also "said he did not know why (Longueil) did this to him, and it upset him."

On the same day, another victim told police that Longueil also lit his hair on fire and then wrestled him. Longueil was toying with a knife, then grabbed the victim from behind "and pressed the knife up against his throat for a short time," police said.

Longueil also pushed the knife’s tip into the victim’s chest, investigators said at the time.

Longueil previously had pleaded to those offenses and had received a deferred sentence contingent on staying out of trouble.

But there were more charges to come. In August 2012, on Canal Street in Brattleboro, Longueil was accused of violating a restraining order.

Eight months later, Longueil was charged in a domestic assault on Marlboro Road. A woman told police Longueil was drunk and "started freaking out," then "cornered her in the bathroom by choking her and then punched her in the face a couple times," court documents say.

Police said Longueil also repeatedly kicked the woman, who was eight months pregnant, and threatened another man with a knife.

After his arrest, Longueil had been ordered to have no contact with the victim. But in May, Longueil was accused of calling her from Southern State Correctional Facility in Springfield.

"You know you could ask to drop the charges, right?" Longueil said in one call, according to court documents.

In another call, he told the victim that "you could have just broken up with me rather than call the cops."

Police said Longueil also sent letters to the victim.

This week, Longueil was sentenced to prison based on his guilty pleas to charges from all four cases. He entered pleas to two counts of aggravated assault, two counts of simple assault, two counts of domestic assault, two counts of obstructing justice, one count of violating probation and seven counts of violating the conditions of his release.
