A woman is presumed dead after going over Niagara Falls yesterday in an apparent suicide attempt, reports WIVB. She entered the water about 6pm on the American side of the falls at Prospect Point, and crews have yet to find her. A tourist reportedly caught it on video and turned the footage over to authorities, who describe it as an "intentional entry." Crews on the Maid of the Mist tourist boat were assisting in the search, reports the Buffalo News. (More Niagara Falls stories.)
