WOODSTOCK, Ont - Their nerves frayed by almost six weeks of uncertainty, the parents of missing eight-year-old Tori Stafford lashed out at each other Friday as they aired out their personal problems publicly.

An afternoon media conference quickly deteriorated into a shouting match between Tara McDonald and Rodney Stafford.

The public spat came the day after McDonald admitted to struggling with an addiction to OxyContin and taking part in methadone treatment.

McDonald says she's trying to regain control of her life while remaining strong for her children.

Stafford criticized his ex-wife for not being honest with the public about her drug problem since Tori's disappearance April 8.

Stafford also says he has a number of suspicions about his daughter's suspected abduction, and he hasn't discounted the possibility that drugs were somehow involved.
