Police said tips were coming in after a family's emotional plea to find a missing pregnant teacher in Maryland.
Laura Wallen disappeared last week around Labor Day, and police found her truck abandoned days later near Columbia Mall and Merriweather Post Pavilion.
The family is offering a $25,000 reward for information.
Wallen is a social studies teacher at Wilde Lake High School in Columbia.
Her current and former students are using the hashtag “#BringWallenHome” to organize and send emotional messages of hope.
“My teacher Laura Wallen is missing,” Lindsay Murray said in a YouTube video. “She's the kind of teacher that kind of genuinely cares about her students, and we all care about her.”
Students and loved ones shared some of their most valuable memories of Wallen.
“There never was a day where you'd walk in her door, and she wouldn't be right there asking how are you, how is your day going,” one student remembered.
“Just pull me into a really tight hug, which I could really use right now. I've always just known you were there,” a Wild Lake High School senior said.
The students sent a message across the internet to one of their favorite teachers: “I want you to know how many people love you,” Murray said. “We are all missing you and looking for you and trying to spread the word so that we can find you and bring you home.”
Police have not found any evidence of foul play, but Family members said it is unlike Laura Wallen to just up and disappear.
The biggest concern right now is for her and her unborn child’s safety.
