The O.P.P. are turning high tech in a effort to resolve to the 30 year old murder of Thera Dieleman.

Using D.N.A. recovered from the murder scene, experts have been able to create a composite sketch of a suspect at the time of the murder and what the man might look like now.

Police hope the images will help narrow down the search by eliminating suspects and possibly lead to new information and eventually an arrest.

The 80 year old was found strangled and beaten in the doorway of her home on Oxford Road 29 in Blandford-Blenehim Township in September of 1988.
