A Maryland man accused of killing his pregnant girlfriend and burying her body in a shallow grave was engaged to another woman at the time of the slaying, police said.
Tyler Tessier, 32, of Demascus, is charged with first-degree murder in the death of Laura Wallen, 31, of Olney, whose body was found Wednesday buried in a field in Demascus. Wallen, a popular high school history teacher, was four months pregnant when she died.
The Washington Post reported that Tessier, believed to be the father of Wallen’s unborn child, admitted his engagement to police in Montgomery County.
“(Tessier) was not honest with either woman,” Montgomery State’s Attorney John McCarthy said Thursday, according to the Post.
Tessier was arrested and charged Wednesday, two days after he stood beside Wallen’s parents during a news conference and pleaded with the public for her safe return. Montgomery County police allowed Tessier to participate in the news conference, despite their belief that he was responsible for her disappearance.
Wallen’s parents were aware of the investigators’ “calculated decision” to allow Tessier’s participation, Montgomery County Chief of Police Tom Manger said Wednesday during a news conference announcing Tessier’s arrest. Detectives wanted to see what Tessier would say at the news conference, and how he would say it.
Wallen’s alleged killer held her mother’s hand as he pleaded for her to come home.
