The family of a woman killed in Elgin County nearly three decades ago is hoping to find some closure.

Elgin OPP say the family of Sonya Cywink is putting up an extra $10,000 for any information leading to the arrest and conviction of Cywink’s killer. Her  body was found at the Southwold Earthworks National Historic Site in 1994.

The reward is on top of $50,000 being already being offered by the provincial government.

Cywink was originally from Whitefish River First Nation on Manitoulin Island. At the time of her death, she was living in the east end of London, Ontario. She was last seen alive in London near the intersection of Dundas Street and Lyle Street at approximately 2:00 a.m. on August 26, 1994.

“Someone out there knows something about this case, even the smallest detail could help,” Detective Inspector Randy Gaynor says. “We urge anyone with information to step forward and help bring this investigation to a successful conclusion.  We certainly want to solve this homicide and bring the person(s) responsible to justice for Sonya and her family.

Investigators are asking anyone with information to contact the Director of Criminal Investigation Services, Ontario Provincial Police at 1 888-310-1122 or (705) 329-6111, or their nearest police authority.
