Body of missing Olney teacher found, boyfriend charged with murder
Tessier, uncomfortable and sweating, had made an emotional plea for Wallen's return at a press conference just 48 hours earlier. It turns out police detectives had intentionally included him in the press conference to see what he might say, with the knowledge of Wallen's family, who held Tessier's hands during the media event.
Montgomery County Police Chief Tom Manger said detectives determined Tessier was the last person to be with Wallen before her disappearance ten days ago. Manger said it is believed Wallen was killed September 3, after last being seen with Tessier on a grocery store surveillance camera a day earlier.
Tessier sent Wallen's sister text messages on September 4, Manger said, but he did not divulge the content of those texts. Those texts were what launched the urgent search for Wallen last week.
