Tragic: Mackenzie Hohl-Sowa, 15, was discovered dead by a walker in Clinton, Massachusetts, yesterday after her family had spent nearly three days searching for her . After nearly three days of searching, her worst fears were realised yesterday when her daughter was discovered dead. Last night Mackenzie's grandmother Sandra Sowa said she had told Mackenzie to be safe as she went out for the night on Friday. She told NECN: 'She was the move of my life. My heart is broken and I don't know how to fix it. 'We used to always have this thing "I love you to the universe". She kissed me and she told me she was going out and I said "be safe".' The grandmother added that they had frantically searched for the teenager after she failed to return home or answer her phone. Investigation: The schoolgirl is believed to have been walking along these tracks when she apparently fell to her death . Tributes: Flowers are left at Clinton High School, where the 15-year-old studied, after her death . She added: '(We were) searching, searching. My grandson, my husband, they walked the tracks. Nobody has called and told us anything, but last night I knew. Don't ask me how, I got in bed, and I said, I just know.' The schoolgirl, who would have been 16 in August, suffered heartbreak two years ago when her father died in 2010. She wrote a heartbreaking open letter to her father which was published in a newspaper. She wrote that she had taken a '180 degree turn around the sharpest corner of life' a year after the tragedy. Family heartbreak: Mackenzie's mother said 'she is still my baby' after discovering that her daughter had died . Her death is not being treated as suspicious and is thought to be a tragic accident. Mackenzie's mother Katie Hohl, who was never married to her daughter's father, described her daughter as 'beautiful, bright and intelligent.' The girl went to Clinton High School. Her mother told Boston.com: 'She was a beautiful, bright, intelligent, wonderful, wonderful girl. 'I’m still in shock. She’s too young. This is not happening. This is not happening. She’s still my baby.' The mother added that they had been putting up pictures of her daughter as they desperately searched for her. In a post on her daughter's Facebook page, she wrote: 'thank you for all your support and help in locating my daughter. She is now at peace and with her dad.'
