INVESTIGATORS believe missing college student Saniyya Dennis threw herself off Niagara Falls following a break-up.
Dennis was last seen leaving her dorm at nearby Buffalo State College on April 24.
Who is Saniyya Dennis?
Saniyya Dennis is a 19-year-old college student who authorities fear may have taken her own life.
Before she went missing she had an argument with her boyfriend, who lives in New York City, according to Erie County District Attorney John Flynn.
Dennis, who grew up in the Bronx, reportedly texted her boyfriend "I think I'm going to kill myself" after he dumped her and ignored 66 of her calls.
After receiving no response she added: "I’m so done with my own life I’ve had enough."
She later spoke to a male friend, and also made references to him about dying by suicide.
The pair would go on to have a four-hour-long conversation that lasted until 10pm.
The male friend, who also lives in New York City, later told police he believed he could talk Dennis out of killing herself.
She was caught on surveillance leaving her dorm and throwing "personal items" in the garbage before boarding a bus alone to Niagara Falls State Park.
Flynn declined to specify what items Dennis threw away but said they led investigators to believe she had no intention of returning to her dorm.
After arriving at the park, Dennis texted her mother: "I love you - I'll call tomorrow."
She also texted her male friend, telling him: "glad we talked."
The teen was spotted by park cameras along a trail towards Goat Island at 12.17am on April 25.
This was the last time she was seen on video.
"An exhaustive search and review of the evidence has been done and it appears that this poor girl took her own life," Flynn told reporters on May 6.
