Over the last several years, the Wisconsin Historical Society says it's found a total of 16 ancient canoes lurking at the bottom of Lake Mendota in south-central Wisconsin.

Tamara Thompson is a maritime archaeologist who helped lead those discoveries.

She suspects that, for millennia, Indigenous people returned to that section of the lake.

She says they may have been stashing their boats for later by burying them under sediment near the shoreline.

What we're seeing really is a parking lot.

The cluster of canoes includes a red oak vessel discovered earlier this year.

It's believed to be 5,200 years old.

That makes it the oldest canoe ever found in the Great Lakes region and one of the oldest found in North America.

Yes. So the shooter has been ID'd as 15-year-old Natalie Rupnow. Her first name was Natalie, but she went by Samantha. Police say she died of what's believed to be a self-inflicted gunshot wound. And what do we know about the survivors? How are they doing? As of late Monday, police said at least two students were in critical condition with life-threatening injuries.

Other victims, including a teacher, suffered injuries that weren't life-threatening. One mother, Marae Jean Charles, has three boys who all go to school at Abundant Christian. And she was relieved that none of her sons were injured, but she also says she expects them to have emotional trauma for a long time.
