Matthew Foerster pleaded guilty to a 2004 home invasion in Cherryville where he also attacked a woman.
He also admitted attacking a Kelowna sex-trade worker in 2005.
Foerster was sentenced to six years for each of the attacks and will serve the time concurrently with his 25-year sentence for the murder of Taylor Van Diest in 2011.
Eighteen-year-old Van Diest was walking along railroad tracks on Halloween night when Foerster attacked her.
His father, Stephen Foerster, was sentenced in May to three years in prison for trying to help his son evade police. (CKIZ)
