Methamphetamine was found in the offending vehicle that killed three people in a crash last month.
Police have told Stuff that methamphetamine, consistent with personal use, was found in the ute driven by Haydn David Clark, 20, who crashed killing himself and a married couple near Thames on April 19.
The Drury man crossed the centre line and collided with a car in which Jocelyn Anne Fielder, 64, and her husband Ian, 66, were travelling, near the Kopu Bridge on State Highway 25.
