New York state police searching for a woman who went over Niagara Falls Saturday evening are reportedly calling the incident an “intentional entry.”

WIVB-TV reports a witness turned video footage of the woman to the authorities, who are now using it in their investigation. State police said the woman appeared to be in her 40s.

The Buffalo News reports search and rescue crews have been unable to find the woman. A two-hour search from above and below that falls has turned up nothing, according to Niagara Falls Fire Department Battalion Chief Mark Fontanella.

Park Police spokesman Randy Simons said it appeared the woman intentionally entered the water to “harm herself.”

Authorities, with the assistance from Maid of the Mist crews, also asked Niagara Falls, Ontario, Canada to be on the lookout for the woman.

Police haven’t released any other information about the woman, according to WIVB.
