Sixteen witnesses are expected to testify in the preliminary hearing of two teenage girls charged with second degree murder. It followed the death last year of a 16 year old girl who's body was found in the bushes behind Wentworth Crescent. The hearing will determine if there is enough evidence to send the case to trial. Six days have been set aside for the hearing: August 16th, 17th and 18th as well as September 14th, 15th and 16th.
