Sentencing is expected today in a New Westminster courtroom for a man who has admitted to the second-degree murder of 17-year-old Surrey woman Serena Vermeersch.

Raymond Caissie entered the plea last month.

Parole board documents show Caissie was considered a high risk to reoffend when he was released from prison in 2013 after serving his entire 22 year sentence for an earlier violent sexual assault and kidnapping in Abbotsford.

Surrey RCMP issued a warning at the time of his release, saying he "has maintained a varied pattern of offending, having offended both violently and sexually, in both an opportunistic and impulsive manner."

Vermeersch was attacked and killed just 18 months later. 

Her body was found near railroad tracks in Surrey's East Newton neighbourhood on Sept. 16, 2014.

She was last seen alive the previous evening, boarding a bus at the corner of 128 Street and 64 Avenue.
