An Endangered Person Advisory was issued Monday for a 15-year-old Hillcrest High School student last seen Friday.

Samantha Hoecherl was last seen after school, 7350 S. 900 East, said Midvale police detective Brian Holdaway.

"She normally rides the bus," he said. "She never got on the bus. We think she was walking home."

Hoecherl was reported missing late Friday night. At first detectives were treating the case as a possible runaway. But Holdaway said investigators weren't so sure Monday.

"After talking to her friends, we can't show that she ran away," he said.

Holdaway said Hoecherl had not discussed running away with any of her friends and did not have any known crisis in her life which would have prompted such action.

In addition to being missing, there is a special concern to find Hoecherl because she suffers from grand mal seizures which are usually triggered when she is "stressed out or in a bad situation," Holdaway said.

Hoecherl does not own a cell phone or have any credit cards. She is about 5-foot-4, 130 pounds with blue eyes and red and orange hair. She was last seen wearing a tan or black coat, as best her parents can remember, Holdaway said.
