Man arrested in Allenstown stabbing on charges of conspiracy to commit first-degree murder



A Barnstead man was arrested Thursday night in Laconia and is accused of helping to plan the murder of an 18-year-old woman found stabbed 15 times earlier this week in Allenstown.

Kyle Buffum, 22, was arraigned yesterday in Concord’s district court on charges of conspiracy to commit first-degree murder. According to the police, Samantha Heath, 18, also of Barnstead, allegedly attacked Andrea Halvorsen of Allenstown. Heath was formally charged with first-degree assault Monday in Hooksett’s district court. Buffum and Heath are both being held at Merrimack County jail – Buffum on $500,000 cash bail and Heath on $50,000 cash bail.

Halvorsen underwent surgery the evening of the stabbing, and she was in stable condition yesterday at Concord Hospital, according to Merrimack Deputy County Attorney George Waldron. Halvorsen is lucid, and her condition appears to be improving daily, he said.

The police are not yet saying how Halvorsen came to be in Heath’s red Mitsubishi on Sunday night when she was nearly killed at the intersection of Deerfield and New Rye roads in Bear Brook State Park. Nor are investigators speculating as to a motive in the crime.

However, Waldron said yesterday, at least one motive has been ruled out by the police: jealousy.

“I can tell you this,” Waldron said, “there is no romantic relationship between Andrea and this Kyle. It’s more calculated.”

All documents relating to the pending court cases of Buffum and Heath have been sealed while the investigation continues, Waldron said.

Halvorsen, Heath and Buffum have all been arrested within the last two years, according to court documents. However, the crimes which they are accused of committing are different.

Halvorsen’s only record not related to driving was an arrest in June for unlawful possession at a party held at Buffum’s then-residence at 46 Concord St. in Concord. Buffum was also arrested that night, according to court documents, and charged with the sale of alcohol to minors. About 30 additional arrests were made at the party.

Before the charge of first-degree assault, Heath’s record included nonfelonies, such as shoplifting and disobeying a police officer.

Buffum’s list of criminal charges, some of which are still pending and some of which he has been convicted of committing, have more depth. They include burglary, fraudulent use of credit cards, willful concealment, several breaches of bails, criminal trespassing, transportation of alcoholic beverages and multiple simple assaults, according to court records.

Two of those simple assault charges were for alleged assaults of Heath on Sept. 5 and resulted in a protective order being included in Buffum’s bail requirements. Those assault charges were pending at the time of his arrest Thursday night. Buffum was arrested earlier this week for breach of bail requirements, but he was released again on bail.

It was first reported that Heath was ordered to keep away from Buffum for his protection, but records and the police now say it was the other way around: Buffum was considered a threat to Heath.

Despite the protective order, both defendants list their address in court records as 6 Amherst Drive in Barnstead, where the police first attempted to arrest Heath on Sunday night following the stabbing. According to the police, Heath ran out the back door that evening to avoid the police, but she was tracked by a state police K-9 unit and arrested after about an hour.

A 911 caller had led the police to Heath that night. The caller and his daughter were driving on Deerfield Road about 8 p.m. when they came upon a bloodied Halvorsen struggling to get away from her alleged attacker, according to the police. The witness gave the police the license plate number of what turned out to be Heath’s car, which the caller said nearly struck Halvorsen as its driver attempted to flee detection.

Both Buffum and Heath have been assigned public defenders and have probable cause hearings pending in Hooksett’s district court. Heath’s probable cause hearing is set for Monday, but Waldron said yesterday it may be postponed. Buffum will have his probable cause hearing Feb. 10.

As my grandmother would say, these kids were not raised they "came up across" (not sure I understand that saying). This is more proof of the impact of the breakdown of the traditional nuclear family. The apple does not fall far from the tree as they say and the parents in this case must be so very proud of their children and how they contributed to the decay of the lives of such young folks. Where are the parents? Let's call them out to explain how someone on this Earth 18 years can turn out to be so irresponsible and heinous.
