He was drafted by San Francisco in the seventh round out of South Carolina State in 2010 and played as a reserve defensive back for five teams in six years from 2010 to 2015.The victims were identified as Dr. Robert Lesslie, 70; his wife, Barbara Lesslie, 69; their grandchildren, 9-year-old Adah Lesslie and 5-year-old Noah Lesslie; and James Lewis, 39, who was working at the home at the time he was shot, authorities said.A sixth person was also shot and survived, officials said.Lewis and the surviving victim — who was in critical condition Thursday morning — were air conditioning techs who were found shot by their work vans, York County Sheriff Kevin Tolson said.Robert Lesslie was a well-known doctor in Rock Hill, ABC Charlotte affiliate WSOC reported. He spent many years working in emergency rooms in the Charlotte area, according to his website biography.The sheriff said, “Dr. Lesslie was a pillar in this community.”“He had treated me in the past,” he said.Robert Lesslie and his wife had four children and five grandchildren, his website biography said.Robert and Barbara Lesslie in a photo posted to Robert Lesslie’s website.The Lesslie family said in a statement, “We are truly in the midst of the unimaginable. The losses we are suffering cannot be uttered at this time.”The family said, “If you would like to do something for the family, Adah and Noah would want you to stock the free pantries and libraries in your community. Barbara and Robert would want you to be good stewards of what you are given, leaving every place better than it was before you got there.”All the deaths are being investigated as homicides, according to the York County Coroner’s Office.The York County Coroner’s Office said Adams was found dead from a self-inflicted gunshot wound at a nearby home on the same road as the Lesslies, following a standoff.“We did recover evidence at the scene that linked Mr. Adams to that area definitively,” Tolson said at a news conference Thursday.A motive has not been determined, Tolson said.“There is nothing about this right now that makes sense to any of us,” the sheriff said.Rock Hill is about 26 miles south of Charlotte, North Carolina.South Carolina Rep. Ralph Norman said Robert and Barbara Lesslie were his close friends.“Through the decades, they made such an incredible impact on our area and the lives of countless people,” Norman said in a statement.“It is impossible to imagine the grief that the extended Lesslie family must be feeling,” he said. “I also want to send my sincere condolences to the family of James Lewis.”Joel and Steven Long, co-owners of GSM Services, the company which employed Lewis and the man who was shot and survived, said in a statement, “Our team at GSM Services is heart broken.”“Both men involved in this incident are long-standing, beloved members of our family at GSM. These men embody the values we strive to achieve at GSM and are family focused, up-beat, and wonderful team members who cared about all the people they encountered,” the Longs said. “In the coming days, our focus is on helping these families and our team members cope with this tragedy.”ABC News’ Rachel Katz and Alexandra Faul contributed to this report.Copyright © 2021, ABC Audio.
