CTV News has learned the National Parole Board has revoked the parole of convicted killer Chris Falconer and that police consider him to be a suspect in an ongoing investigation.

The board won't say what that investigation is, and police won't confirm if it is the Amber Kirwan murder investigation, but Falconer has been behind bars since he was picked up in New Glasgow in November on a parole violation.

In a decision released this afternoon, revoking his parole, the board wrote:

"In October 2011 you were questioned by police regarding your possible involvement in a serious offence they are currently investigating."

Amber Kirwan, 19, was last seen leaving a pool hall in New Glasgow on October 9, 2011 before she was reported missing.

Her boyfriend said she was supposed to meet him just up the road from Dooly's at Big Al's convenience store, but Kirwan failed to show up.

An extensive search involving local police, RCMP and ground search and rescue crews was launched shortly after her disappearance.

Her body was discovered on a logging trail just off the Heathbell Road on November 5, roughly three kilometers from Falconer's stepsister's home.

Police spent more than a week combing the grounds of the home in Heathbell as they gathered evidence in the case and Falconer was arrested in New Glasgow on a parole violation.

Police also seized a 2002 Chev Impala in connection with the Kirwan investigation shortly after her body was found. While police didn't reveal who owned the car, neighbours told CTV News in November it belonged to Falconer.

As part of today's decision, the parole board said:

"You are currently a suspect in an ongoing police investigation."

However, RCMP would not comment on the case today.

"The police will not comment on who is or is not a suspect," said RCMP Cpl. Bill Rudolph. "Should there be a charge laid in relation to any case, generally speaking, at that time we would release the name and relation of the charge."

The parole board acknowledges Falconer is a subject of interest to police and said:

"The board has concluded that a resumption of release at this time would create undue rick to the public."

Falconer was one of two men convicted of second-degree murder in the killing of cab driver Robert LeBlanc on Heathbell Road in 1998, but he was released on full parole in May.
