Police: Couple behind Allenstown stabbing planned second murder and future in Florida

The stabbing of an 18-year-old Allenstown woman four months ago was part of a multi-victim murder plot hatched by two young lovers seeking revenge and life anew in Florida, according to a police affidavit unsealed Friday in Merrimack County Superior Court.

The document, previously withheld pending further investigation, contains excerpts from more than 70 pages of messages sent between the phones of the two suspects, 22-year-old Kyle Buffum and 19-year-old Samantha Heath, in the weeks leading up to the Jan. 26 attack, in which Heath is accused of stabbing the woman repeatedly with a knife.

“I was so turned on when you robbed that store,” Buffum allegedly wrote four days before the assault. “Imagine what bringing me the body of someone I hate would do for me.”

Buffum and Heath have each been charged with multiple felonies in the case, including conspiracy to commit murder, and are being held in county jails. The victim, Andrea Halverson, suffered roughly 15 stab wounds in the attack, including in the chest, stomach, legs, arm and back. She underwent surgery that night and has been recovering in the months since, according to prosecutor George Waldron.

Heath and Buffum have been romantically involved in the past, but the relationship was tested in September when Buffum was charged with assaulting Heath and prohibited from contacting her.

They stayed in touch anyway, according to the text messages and statements from Buffum, and began plotting the stabbing at least as early as Jan. 10, the affidavit said. Allenstown police Chief Paul Paquette said in the affidavit that the messages show Buffum masterminded the attack, and that the couple also planned to rob gas stations and murder a second person, identified as “Luther LKU,” before fleeing to Florida.

They also showed that Heath was pregnant at the time, Paquette wrote.

The extent of the couple’s relationship with Halverson remains unclear, although they each attended a party last June at Buffum’s then-residence in Concord. That event was ultimately broken up by the police, and Halverson and Buffum were each charged with alcohol-related offenses.

Halverson appeared to be on friendly terms with Heath at the time of the attack, according to Heath’s and Buffum’s messages. The two women appeared to have planned to meet up Jan. 11, but Halverson backed out at the last minute.

“Please don’t blame me tonight on me I was ready to do it,” Heath wrote Buffum that day (the texts are written as they appear in the affidavit). “I am ready. Shes’s find now, just excited to see me, So I got her trust.”

But by Jan. 22, nothing had happened, and Buffum appeared to be growing impatient, according to the affidavit.

“I’d really appreciate if you took care of andrea so I can let some of my hate toward you go,”

“It’ s fine I’ll get her but ky. I’m losing you either way,” Heath wrote that day. “Killing these people will make you feel better but you’ll still hate me.”

By Jan. 26, though, Heath appeared to have a cemented plan, according to the messages.

“Okay I think I know how I’m gunna do do it,” she wrote.

“How?” Buffum replied. “Just be careful please. Don’t give her any chance to run or call for help.”

“Ohh. Uhm. So what I’m gunna do is when I’m driving her back like on the road from concord to Allenstown and I’ll stab her,” Heath wrote back. “Like in the car then pull off into bear brook and like finish it there. I am a little nervous but honestly excited….”

Halverson was found that night at Bear Brook State Park by a driver and his teenage daughter. She was seated near a snowbank in front of a small red sedan, wearing a bra and jeans and screaming for help, the driver later reported, according to the affidavit. The car sped off, he said, nearly hitting Halverson in the process.

Heath was arrested the next day after fleeing into the woods near Buffum’s Barnstead residence. Her car, a red 1996 Chevrolet Geo Prism, was found outside the residence, with red stains on it inside and out, the affidavit said. An officer noted a knife on the backseat, with a roughly 5-inch blade and what appeared to be blood on it.

This report was very disturbing to read. Beancounter, I think GWTW meant life in prison is too good for this pair. In other words, that poster favors the death penalty for them, if/when convicted that is. I could be wrong, but that's how I read it.

Thanks for explaining that. I misread the post. Sorry, G-dub

Life in prison for these 2 ....just seems wrong. Maybe its just me.

You're kidding, right? They tried to murder someone in cold blood.
