Saniyya Dennis was a 19-year-old engineering student at Buffalo State College who was last seen leaving her campus residence hall on the evening of April 24, 2021. Reportedly an honor student, she had been in an argument that day which ended her relationship; later she told a friend she was thinking about suicide and attempted to contact her ex. Surveillance shows her discarding personal items and boarding a bus to Niagara Falls State Park alone. Park cameras captured her on a trail near Goat Island shortly after midnight on April 25, and her cell phone last pinged in that area before losing connection about 1:20 a.m. Search teams scoured the park; scent dogs lost her trail near the water’s edge and no body has been recovered.

The Erie County District Attorney’s Office stated they believe Saniyya died by suicide and found no evidence of criminality, but the investigation remains open. Her family disputes that conclusion and has expressed concerns that foul play may have been involved. If anyone had contact with Saniyya the night of April 24–25 or saw her near Goat Island, please share what you know.
