Woman, 20, is killed after boat capsized in Lake Michigan at 2:40am and she was pinned against breakwall in accident that sent four women and two men to hospital

Six people have been pulled from Lake Michigan after a boat collided with a brick wall and capsized. 

A seventh woman, 20, died in the 4am horror smash, with divers finding her body pinned underneath the boat and up against the breakwall. 

Chicago Fire Department confirmed that the accident happened near the Navy Pier on Friday morning, in an area known as the ‘playpen’. 

Four women and two men were saved from the water, and are all aged between 20 and 30 years old. 

Authorities responded to calls about the boat in distress, with one person remaining in a critical condition. 

The other five who were pulled from the water are currently in a serious condition in hospital as the search for the seventh continues. 

Fire officials launched a search for the missing woman and discovered her at around 5.30am this morning before handing the investigation over to the police.

A breakwall, typically built outside of a harbour, diminishes damage due to battering by the waves. 

The boat is understood to have been returning to shore when it struck the wall and capsized.
