Lyons, 25, was last seen Wednesday around 4 p.m. at the exhibition grounds on Saunders Street. He was heading to the gym and planning to return home that night, but he never arrived.

His gym bag was found Thursday on a footpath. The bag contained all of his personal belongings, including his wallet and credit cards.

Nathalie Pitre-Sappier, a family friend, said Lyons was taking medication to treat depression and seizures.

"The last time he used his debit card was at the liquor store," she said. "That's our concern, that he mixed medication with alcohol. Something may have happened. He may be disoriented."

On Sunday, the search party said a group prayer before breaking off into smaller groups.

The Fredericton Police were also looking for Lyons Sunday. The marine unit spent its second day on the St. John River. They said there is still no indication he went into the water, but they are trying to cover all their bases.

Lyons is 5'10" tall, 130 pounds, with short blond hair.

The police are asking anyone with information about his whereabouts to contact them.
