CTV News has new details about what led to the arrests in the case of three family members shot and killed in a rural farmhouse near St. Leon.

In November, 2005, the bodies of Fernand Labossiere, 78, his wife Rita, 74, and their son Remi, 44, were found in the burned out shell of the family's western Manitoba home.

Now court documents describe an extensive RCMP investigation that included phone taps, undercover operations and informants.

They also reveal more about how the three, who were found in the basement burned beyond recognition, died.

How they died

According to autopsy reports, Rita Labossiere was shot in the right side of her neck, bullet wounds were found in Fernand Labossiere's brain, below the rib cage, and in his back. Remi Labossiere was shot in the head and left thigh. The murder weapon was never found.

Two years later police arrested and charged Rita and Fernand's son Jerome Labossiere with three counts of first degree murder and three counts of conspiracy to commit murder. Two other men, Michel Hince and Jeremie Toupin are also charged.

According to phone records, Jerome Labossiere and Michel Hince spoke several times on the day before the murders.

The documents also contain a record of a witness who told police that Jerome Labossiere said he wanted Remi dead a year before he was killed.

The witness quotes Jerome as saying, "Do me a favour, get rid of my brother. Do an accident for me."

According to police documents, only days after the murders Jerome Labossiere told witnesses "Well, the parents were a surprise." Witnesses say he didn't elaborate.

The documents also reveal another man accused, Michel Hince as saying "I want to kill myself for what I, uh for what I did on the farm."

He made a gun symbol to his head, and according to the documents Hince also admitted to receiving a down payment for his house in return for the killing.

Jerome Labossiere had some bad debts, and at the time of the murders, he was in a legal battle over the family farm valued at more than $1 million, according to court documents.

In a will dated August, 2000, his brother Remi Labossiere left proceeds from the estate to six nephews and nieces. However a second will, written shortly before the murders, left all of the property to Jerome Labossiere and his wife, Claudette.

More arrests may come

Investigators have interviewed more than 100 people -- some several times.

Police say more arrests may come, as one other suspect has been identified and investigated but never charged to date.

According to police documents that one person told Jerome he shot Rita "between the t*ts"

None of the allegations in the documents have been proven in court. Jerome Labossiere, Michel Hince and Jeremie Toupin have not been convicted in the murders, and are considered innocent until proven guilty.

The murders in St. Leon preceded the murders of two more members of the same family in their home on Chokecherry Cove on April 20, 2008.

Kelly John Clarke, 38, is now charged with two counts of first degree murder in the deaths of Joel Labossiere, 34, and his pregnant wife Magdelena, 33.

They were shot execution style. Joel is the nephew of Jerome Labossiere, and was also in a legal fight with Jerome over the family farm.
