NANAIMO — A woman has been found guilty of the reduced charge of second degree murder and for interfering with the remains of her former boyfriend.
Paris Jayanne Laroche, 28, was on trial earlier this year charged with first degree murder for the death of Sidney Joseph Mantee.
She also pleaded not guilty to interfering with a dead body.
On Friday, July 19 by veteran BC Supreme Court Justice Robin Baird in Vancouver, who oversaw the lengthy judge-alone trial, released his decision in an oral ruling.
Justice Baird wasn’t convinced Laroche intended to kill Mantee until she woke up at about 4 a.m. on March 5, 2020 — thus in justice Baird’s opinion, the premeditation factor required for a first degree conviction was not met.
“It was a matter instead of revenge,” Baird said, adding the evidence showed the brutal killing was not an act of self-defence, noting Mantee was unarmed and not a threat at the time.
While Laroche will be handed an automatic life in prison sentence, it will be up to the judge to decide parole eligibility between 10 and 25 years.
Mantee, 32, was killed by Laroche in the early morning hours of March 5, 2020 at the Nanaimo apartment unit the pair shared, a contention her defence team acknowledged as true during the trial.
Lead defence attorney Glen Orris also didn’t dispute undercover police evidence and confessions made by Laroche to multiple people that after she killed Mantee she cut up his remains into many pieces and disposed of him around Nanaimo, including at public parks over the course of many months.
Orris argued her client’s actions were unplanned acts of self-defence.

The trial heard testimony from a close friend of Laroche, Robyn Bartle, who said Laroche confessed to the killing a little over 13 months later, indicating she’d beaten Mantee with a hammer.
Bartle, aware Mantee was previously a reported missing person, was under the impression he had moved to Victoria after the pair had split up.
She testified Mantee abused Laroche and animals and threatened her friend’s beloved cats and family.
The following day Bartle filed a report with Nanaimo RCMP, triggering an undercover police operation several days later at her apartment unit.

Laroche then confessed to a pair of undercover police officers within several minutes after meeting her at her apartment unit.
She said Mantee was sleeping face-down on a living room mattress when she hit him multiple times in the back of the head with a small graphite sledgehammer, then slit his throat.
Laroche then took police to various sites around Nanaimo, including Neck Point Park and Pipers Lagoon Park, where bone fragments of Mantee were found.
“I broke him down piece-by-piece in the bathtub like an animal,” Laroche told the undercover officers.
She also relinquished the sledgehammer she used to bludgeon Mantee, as well as tools and other items associated with dismembering his remains.
Defence lawyer Orris Orris told the trial mistreatment by Mantee of one of Laroche’s cats the night before the killing put his client over the edge.
“She undertook the acts in order to defend herself…having been trapped in the situation she was in and feeling that way, she had no alternative.”
Notably, Crown prosecutor Nick Barber stated while Laroche suspected her cat had been abused by Mantee, she couldn’t confirm it as fact before she slaughtered Mantee.
Barber argued Laroche’s actions were clearly pre-meditated and unreasonable.
“If she had been afraid or felt that she needed to act in self-defence there were so many options. She could have gone to work, gone to the authorities, or gone to friends or just done nothing because Mr. Mantee was asleep,” Barber argued at trial.
Barber referenced post-offence conduct by Laroche, including using the same knives she used to cut up Mantee to prepare meals.
Laroche, who didn’t testify in her own defence, was arrested second time with charges officially laid in March 2022.
She’s been in custody ever since.
Laroche unsuccessfully applied to be released on pre-trial bail last summer.
