— They went to Ohio Bike Week on Saturday
Two teenagers went missing Saturday after saying they were going to a friend's house but went to Sandusky for Ohio Bike Week in a taxi instead.
Huron police and the Sandusky police departments have scoured locations where the girls might have gone, but as of this morning they had not been located.
Zoe Koehler and Maggie Freeman, both 13, were staying at a grandmother's house. They said they were going to a friend's house, but instead the girls and a friend took a taxi to Sandusky, police said. The friend called for a ride home, but Koehler and Freeman remained downtown.
The last communication from the girls was to a friend via Snapchat at about midnight, and a cell phone locator placed them in Sandusky at 1:21 a.m., police said.
Koehler was wearing jeans and a white T-shirt with a print. Freeman was wearing jeans with a light plum shirt.
Anyone with information on the girls is asked to call Sandusky police at 419-627-5863 or Huron police at 419-433-4114.
