A fourth person has been charged in connection with the murder of a teen who was shot to death during a local basketball game in Malton earlier this month. But police say they are still looking for one more suspect in the case.

A 20-year-old Toronto man, Courtney Dawkinsl, was arrested Wednesday and charged with first-degree murder in the death of 17-year-old Adrian Ducas.

Two other Toronto men, Kevaughn Tulloch, 20, and Maurice Raphael, 23 also face first-degree murder charges in the case.

Cassandra Elizabeth Scavone, 20, has been charged with being an accessory after the murder.

Ducas was at the Malton Community Centre on July 3 when two basketball games were being played. Several men came into the centre and got into a fight with the teen.

The teen was fatally wounded.

Police have issued an arrest warrant for Christopher Raphael who is believed to be a cousin of one of the suspects in custody. He is also wanted for first-degree murder.

Authorities warn anyone who is helping the suspect evade police will also be subjected to charges.
