MICHIGAN CITY, Ind. (AP) — Indiana conservation officers say choppy waters are hindering the search for a missing teenager in Lake Michigan.

They say 17-year-old Rahem Mason of South Bend has been missing since witnesses reported seeing him go underwater Saturday evening near Washington Park in Michigan City and not resurface. The water had been closed throughout the day due to dangerous waves and currents.

Officers say divers from multiple agencies met Monday morning and determined 5-foot waves made it unsafe to conduct dive operations.

The Michigan City Fire Department launched a drone to search the park area from the air, and a sonar search by boat was possible.

Officers say divers plan on going in Tuesday if the weather allows it.
