The decomposed body found this weekend in a Louisiana bayou was identified Monday as that of a teacher missing for three months, the New Orleans Police Department said.

The statement said Terrilynn Monette, who was last seen March 2, was identified through dental records. The death was ruled a drowning, and there were no signs of trauma to the body, police said.

On Saturday, a diver with the Slidell Police Department who was volunteering to dive the waterways in the search for Monette found her Honda Accord in the bayou.

Monette's mother, Toni Enclade, told CNN earlier that she had been notified a body was found.

Enclade said she does not know when she will be given a final answer. "To know that she could have possibly been there for three months," she said, overcome with emotion.

"I can't even begin to go there right now," she said. "I'm in shock. I can't believe this. I just can't believe this."

Monette, 26, was last seen leaving Parlay's Dream Lounge in New Orleans, where she had been celebrating with friends her nomination for a "Teacher of the Year" award.
