A Porter County teenager has gone missing after swimming with friends at Portage Lakeshore Park.
15-year-old Corey McFry was in the lake with three friends in four foot waves when he disappeared.
Police say McFry either stepped off the sandbar the group was on, or was knocked off and went under.
Two friends looked for McFry, while another called 911.
No lifeguards are on duty where McFry went missing.
Crews did not find the teenager Sunday evening and are expected to resume their search Monday morning.
