CALEDON, Ont. -- Provincial police are offering a $50,000 reward for any information leading to the arrest and conviction of the person responsible for the 2010 murder of Sonia Varaschin of Orangeville, Ont.

Police say the investigation into the murder of the 42-year-old nurse is ongoing and they are as committed to finding her killer today as they were when the investigation began.

Varaschin was reported missing on Aug. 30, 2010, after she failed to show up for work.

Her blood-stained car, a white Toyota Corolla, was found in an alley the same day.

Days of ground, air and trail searches of the Orangeville area -- which is predominantly rural -- failed to find traces of the missing woman.

Remains discovered days later in a wooded area in Caledon -- northwest of Toronto and about 12 kilometres from Orangeville -- were later confirmed as Varaschin's.
