COLLINGWOOD - A British Columbia man has been arrested in connection with the killing of a Armstrong, B.C. teen.

Police arrested 26-year-old Matthew Foerster on a Canada-wide warrant at a Collingwood motel on Wednesday morning. He's been charged with second degree murder in connection with the death of 18-year-old Taylor Van Diest, who was found badly beaten last October near railway tracks in Armstrong; she later died in hospital.

Police have also charged Foerster's father, Stephen Roy, with obstruction and accessory after the fact.

Matthew Foerester's arrest was made by B.C. RCMP officers with the assistance of Collingwood OPP officers, and the Ontario division of the RCMP.

The younger Foerester has also been charged with one count of sexual assault and unlawful confinement in connection with the April 12, 2005 sexual assault of a Kelowna woman. Additional charges have been laid in connection with a home invasion that took place Oct. 19, 2004 in Cherryville BC, in which a 19 year old young woman was assaulted.

Investigators are continuing their efforts to establish a detailed time line of Matthew Foerster's activities on the day and night of Van Diest's murder on Octo, 31, and his travel and activities from December, 2011 to March, 2012.
