The Lesslie family has also reflected on the "outpouring of heartbreak, shock, grief, and support from our family, friends, and community." "We are truly in the midst of the unimaginable. The losses we are suffering cannot be uttered at this time," they wrote in a statement released through the York County Sheriff's Office. "While we know there are no answers that will satisfy the question "why,' we are sure of one thing: we do not grieve as those without hope." "To that end, our hearts are bent toward forgiveness and peace. Toward love and connectedness. Toward celebration and unity. We honor all of those involved in this story with prayers and compassion specifically for the Shook family, the Lewis family, and the Adams family," the statement continued. Although investigators are not yet commenting on what may have motivated the shootings, York County Sheriff Kevin Tolson has cited unspecified evidence the former NFL pro left behind in the 70-year-old physician and author's home that indicated he was the suspect. At a press conference on Thursday, Tolson said that Adams was living in his parents' home, which is on the same street. Adams, Tolson said, was found early Thursday morning in a bedroom of his parents' house, dead from a self-inflicted gunshot wound to the head. Adams played college football for the South Carolina State Bulldogs before being selected in the seventh round of the 2010 NFL Draft by the San Francisco 49ers. He last played with the Atlanta Falcons in 2015.
