Investigators are not saying what they found inside of Wallen’s condo or in her car.

The Wilde Lake High School teacher never showed up on the first day of school, and the last time family members heard from her was in a text message on Labor Day.

Wallen's boyfriend, who she's known for 10 years, said she is four months pregnant and excited to have a baby.
