The U.S. Coast Guard and local fire departments have been searching since Monday evening for a 20-year-old man whose kayak capsized in Lake Michigan near Highland Park.

A 911 call was made around 10 p.m. Monday after a 20-year-old man was calling for help in the 200 block of Bluffs Edge Drive in Lake Forest.

Police learned that the man was kayaking with another 20-year-old man, identified as Sebastian Duncan, on Lake Michigan near Highland Park. The two men were on kayaks when they capsized due to the rough water and high winds.

The one man swam for an hour before getting to safety on shore where he asked for help from a resident who called 911.

Rescuers have been using numerous boats and a helicopter to search the water. Land searches along the shore are also being conducted. The search was called off around 1:30 a.m. but resumed later Tuesday morning.

Authorities said that the two men launched the kayaks from the Park Avenue Beach in Highland Park. Rescuers are unsure of the exact area where Duncan was last seen but they were mainly searching between Lake Forest and Highland Park.

Neither of the men were wearing life jackets.

It was originally reported by the Coast Guard that Duncan was a Northwestern University student; however, the school says he is not a student.
