Kevin Porter, also known as Kevin Jamar Porter, 38, of 354 Boston Post Road, Sudbury, Mass.

NASHUA – A Sudbury, Massachusetts man with a criminal history that includes voluntary manslaughter and assault with a deadly weapon is now in Nashua police custody, the result of his arrest over the weekend on charges accusing him of possessing cocaine, threatening to harm others, smashing two doors and violating his probation.

Kevin Porter, who also goes by Kevin Jamar Porter, 38, of 354 Boston Post Road, Sudbury, was taken into custody Sunday after police were called to a residence at 10 Amherst St. for reports of a disturbance and a man and two women fighting inside, police said.

Upon arrival, officers were told that the man, whom police identified as Porter, had allegedly kicked down a door in the building. They also discovered he was in possession of a knife, in violation of his probation as a convicted felon.

Additional charges were added as officers and detectives investigated the incident, police said. In all, Porter was charged with one count each of possession of cocaine; possession of crack cocaine; criminal threatening; and falsifying physical evidence, all Class B felonies; and two counts of criminal mischief and one count of resisting arrest or detention, Class A misdemeanors.

Police said Porter was charged under the convicted felons statute, and that they also charged him as a fugitive from justice after discovering that he was wanted by Massachusetts authorities for an alleged probation violation in that jurisdiction.

Upon officers’ attempts to take Porter into custody, police said, he resisted their efforts by allegedly refusing to put his hands behind his back, forcing officers to carry him to their cruiser.

The second charge of criminal mischief was added after police brought him into headquarters for booking ñ he allegedly damaged an interior sprinkler head while housed in the detention area, police said.

Porter then allegedly swallowed what police said “appeared to be a small baggy,” which Porter told them contained narcotics. He was subsequently transported to a local hospital for evaluation, police added.

Porter was at some point taken to Valley Street jail, where he was ordered held pending an extradition hearing scheduled for June 22 in Superior Court.

The location of the alleged incidents is a group home managed by a local social services agency, according to police. After arresting Porter, the officers spoke with two residence supervisors, as well as the two women Porter was reportedly arguing and fighting with.

The employees told officers they called police “when Kevin wouldn’t calm down,” and that they determined he had allegedly broke a door down.

In speaking with the two women, who are cousins, police said one of them told officers she had been “arguing with Porter throughout the night.” Eventually, he allegedly “kicked in the door to the room” in which she was staying with her cousin.

The three had been “hanging out” with “no issues” for much of the night, but around 4-5 a.m., the woman said, “Kevin became increasingly more difficult to deal with,” alleging that he “kept entering their room unannounced, asking for items and bothering them,” police wrote in their reports.

Upon entering the room, the women told police, Porter allegedly lifted up his shirt to reveal a knife, which they said was “attached to his hip.” When one of them asked Porter if “he was going to hit her,” police said he responded “something to the effect of ‘if I have to.'”

One of the women told police Porter “had previously informed her of how he had served prison time for stabbing someone,” police said in their reports.

The woman added that “she was scared that Kevin was going to stab her.”

The women also said Porter “was bragging about spending time in prison … ” and he allegedly showed them a news article on his phone “detailing how he had been convicted of manslaughter for stabbing someone.”

According to archived news reports, Kevin Porter, age 30 at the time, pleaded guilty in October 2011 to one count each of voluntary manslaughter, assault and battery with a deadly weapon causing serious bodily injury, and assault and battery with a deadly weapon, in connection with the 2008 murder of Framingham resident Jeffrey Weaver.

Porter had initially been charged with first-degree murder, the reports state, but later agreed to enter the guilty pleas to the lesser charges as part of the plea deal.

He was sentenced to 9-12 years in MCI-Cedar Junction in Walpole. It’s not clear how much of the sentence Porter served before being released.
