The organization confirms a man was found dead at Kamloops Regional Correctional Centre on Monday, but isn't revealing his identity or the circumstances around his death.
B.C. Corrections says police were immediately notified and the B.C. Coroners Service is investigating.
It is the second inmate death at the same facility in the past few months, after 20-year-old Dylan Judd was found unresponsive in his cell during morning checks on Nov. 10.
Cindy Rose of B.C. Corrections says every in-custody death is a tragedy that is taken very seriously.
