Missing Olney woman found dead, boyfriend charged with her murder


A missing pregnant teacher from Olney, Maryland, was found dead Wednesday in a shallow grave of a wooded area, police said, and her boyfriend was charged with her murder.

Howard County schools officials said they sent a crisis team Thursday morning to Wilde Lake High School and Murray Hill Middle School, where Wallen had previously taught, to support students and staff members.

Wallen's family received text messages from her cellphone September 4, according to Manger. In the texts, Wallen stated she was pregnant with her ex-boyfriend's child, not Tessier's.

"It's unreal. It's like one of them bad Lifetime movies that you just like yeah I know what's going to happen in the next 5 minutes of the movie, like it's not real", one speaker said. The acquaintance refused to assist him.

Investigators are not saying what they found inside of Wallen's condo or in her vehicle. Now, police said one of the speakers at that press conference was likely her killer.

It reads like a page ripped out of a novel like Gone Girl (at least the first part), but it's a tragedy all too real: Police are accusing Tyler Tessier of murdering his pregnant girlfriend, Laura Wallen, and then participating in a press conference in which he posed as the grieving significant other.

While speaking to reporters Wednesday night, Manger said Tessier was already a person of interest at the time of Monday's news conference, after police identified "a couple of inconsistencies in information that he'd given us".

Police are not sure of Tessier's motive, but he has been charged with murder. He said she was an "outstanding teacher" and said the school community was in shock. The photo sent by Wallen showed the same field where her body was located, police said. "We just want to know she's OK".

The "Gathering of Hope" event scheduled for Wednesday evening has been canceled, the school system said.

But police now believe he killed Wallan and buried her in a shallow grave near Damascus, Maryland.

The property owner had no involvement in her killing or burial, Manger said.

Superintendent of Howard County Public Schools, Dr. Michael J. Martirano, extended his sympathy to Wallen's family.

Although investigations are now under way regarding the possible motive behind the murder, speculations are doing rounds regarding Tessier's possible involvement with another woman, who was also interviewed by the police, Heavy.com reported. He listened as her father, Mark Wallen, offered a $25,000 reward for her safe return. The property had open fields and woods, police said.

Manger said Tessier's appearance at the news conference was a "calculated decision" made by police and Wallen's family. "It was done with the approval and knowledge of the victim's family", Manger said.
