NASHUA – After having arrested him twice in three days on drunk driving and criminal mischief charges, Merrimack police had no trouble identifying Kenneth Robertson as their suspect on a new set of allegations two days later.

The result was the same: Robertson, 51, of 246 Daniel Webster Highway, was taken once again into police custody, this time on more serious charges accusing him of pounding and kicking at a neighbor’s door and threatening to kill her, then allegedly walking toward an officer, putting one hand behind his back and stating, “I could’ve killed you (expletives).”

While the charges stemming from Robertson’s first two arrests, on Nov. 12 and 14, are misdemeanors, his third arrest resulted in a Class B felony count of attempted burglary, which moved Robertson’s arraignment to Hillsborough County Superior Court South under the felonies-first system.

At the arraignment, which took place Friday, Robertson entered not guilty pleas to the five charges, which in addition to the attempted burglary charge include two counts each of criminal threatening and breach of bail, all Class A misdemeanors.

Likewise, the charges from his first two arrests also are misdemeanors, therefore those arraignments are being handled in Merrimack District Court. The charges include one count of driving while intoxicated on Nov. 12, and one count each of criminal mischief and breach of bail on Nov. 14.

At the time of his latest arrest, Merrimack police said Robertson refused the services of a bail commissioner, but the amount of bail set at his arraignment wasn’t specified in court documents.

According to police reports and court affidavits, the series of incidents that led to Robertson’s most recent arrest involve the most serious of the allegations against him.

Police said a neighbor of Robertson’s called late the night of Nov. 16, reporting that a man was attempting to break into her apartment and was threatening to kill her.

Speaking to arriving officers, the woman identified the suspect as “a man she knew as Ken,” and that he lives in the same complex.

She told officers he had been pulling on her slider door, attempting to gain entry, while allegedly stating “I’m going to kill you,” police said.

Although Robertson had left before officers arrived, the alleged victim’s brief description was sufficient for them to identify him as Robertson, who, they said, was known to police “due to numerous recent incidents (and) arrests.”

Robertson allegedly demanded to be let in the woman’s apartment, police said, and told her to “get your (expletive stuff) together.” At that point, the alleged victim said, Robertson was “within inches of the sliding glass door” and was “looking directly at her,” police wrote.

While speaking with the woman, police said they found that the exterior screen door had been “violently pulled off its track,” allegedly by Robertson. They also observed marks on the glass door that they said were consistent with it being kicked.

Police said that after talking with the alleged victim, they went to Robertson’s apartment and, finding the front door ajar, entered the residence and located him.

He “appeared disoriented and (was) unsteady on his feet,” police said in reports. When questioned, Robertson “admitted to being at (the woman’s) residence and knocking on her slider door,” but, according to the reports, told police that “he thought it was his sister’s home.”
