Luna Island is a small island between the American Falls and Bridal Veil Falls that, along with the Horseshoe Falls, make up the popular tourist draw.

Authorities are using unmanned aircraft and underwater units in the investigation.

The family reportedly lived in Niagara Falls.

I cant even bare to write a post about her and share memories, wrote Mich Molina.

I am literally sick to my stomach and I cant even deal with the emotions I am feeling. Just know her and her children are dearly loved by me and my children.

Last year a mother from Illinois died, and her son survived, after she jumped with him from a 90-foot cliff onto the frozen banks of the Niagara Falls gorge.
