The Associated Press on Thursday said former NFL player Phillip Adams was the triggerman who shot and killed five people in Rock Hill, South Carolina on Wednesday afternoon before killing himself. The wire service sourced his identity to “a source who was briefed on the investigation” who was not authorized to speak publicly.

WCNC-TV, the NBC affiliate in Charlotte, reported Thursday morning that Adams’ father, Alonzo Adams, “came forward” to one of its reporters to say that “he believed football played a role in his son’s actions.”

The victims were Dr. Robert Lesslie, 70, and his wife, Barbara Lesslie, 69. Their grandchildren, Adah Lesslie, 9, and Noah Lesslie, 5, were also killed. James Lewis, 39, was the fifth person killed. ABC News reported that Lewis was working at the home when he was shot.  A sixth person was shot and was seriously wounded.

The AP said Adams had been Dr. Lesslie’s patient. Adams’ parents live near the Lesslie home, and Adams grew up in Rock Hill, where the shooting occurred.

Alonzo Adams, the gunman’s father, “offered prayers for the Lesslie family,” WCNC said.

Phillip Adams played two years with the Oakland Raiders, one year with the Atlanta Falcons, one year with the New England Patriots, one year with the New York Jets, one year with the Seattle Seahawks, and one year with the San Francisco 49ers, online records indicate. He was a defensive back between 2010 and 2015.

Authorities said early Thursday that they had identified “the person we feel is responsible” but did not immediately release his name.

“We found him in a nearby house,” the York County, S.C. Sheriff’s Office said on Twitter. “There is no active threat to the community.”

An online biography says Dr. Lesslie had been practicing in the area since 1981.

“Dr. Lesslie lives in Rock Hill with his wife, Barbara and their golden retriever, Moses, several miniature horses, goats, donkeys, chickens and a lot of bees,” the bio reads. “They have four grown children and eight growing grandchildren. He enjoys golfing, traveling and bagpiping. He is a regular columnist for YC magazine, an active member of his church, as well as an accomplished author. His series of books offer hope and wisdom for his readers’ overall health and well being based on his years of experience in the field of medicine.”

Authorities have called a 2:00 p.m. news conference Thursday where new details are expected.
