Man serving life for first-degree murder dies after 5 months behind bars

AGASSIZ, B.C. - A man who served just five months of a life sentence for first-degree murder has been found dead in his cell at the Kent maximum security prison in B.C.'s Fraser Valley.

Prison officials say 40-year-old David Langlet was found unresponsive in his cell last Friday.

Langlet had been behind bars since December following his conviction for the June 12, 2000 targeted shooting of 27-year-old Shane Preece.

Surrey RCMP reopened the cold case last year and arrested and charged Langlet in October.

Prison officials have not said what caused his death.

A release from Kent Institution in Agassiz, B.C., says police and the coroner have been notified, and Correctional Service Canada will review the circumstances of the death.
