Twinsburg paramedic Demetrius T’Juan Butler shot multiple times and killed his fiancee, Olivia “Liv” Hamey, 35, in the basement of her Goodyear Heights home as her children, an 11-year-old daughter and 7-year-old son, tried to sleep upstairs. He then went to his mother’s house, where he committed suicide in the driveway (1431 Virginia Ave).
