A man charged in the brutal Halloween night slaying of 18-year-old Taylor Van Diest will make his first appearance in a Kelowna courtroom Tuesday morning.

Matthew Stephen Foerster, 26, faces one count of second-degree murder after being arrested last week at a motel in Collingwood, Ont.

Van Diest was found fatally injured and unconscious in bushes near railway tracks in Armstrong, B.C. on Oct. 31. She later died in hospital.

RCMP Insp. Brendan Fitzpatrick has confirmed Foerster is also a suspect in two unrelated crimes, including a 2005 sex assault of a Kelowna escort and a 2004 assault and home invasion.

His father, 58-year-old Stephen Roy Foerster, has been charged with obstruction of justice and accessory after the fact in relation to Van Diest's murder.
