Former NFL player Phillip Adams was identified as the gunman in a mass shooting in South Carolina that saw him kill five people before he ultimately killed himself, per TMZ Sports.

According to TMZ, Adams killed five people, including two children, on Wednesday down in Rock Hill, South Carolina. The victims were identified as 70-year-old Dr. Robert Lesslie, his 69-year-old wife, Barbara Lesslie, and their grandchildren, 9-year-old Adah Lesslie and 5-year-old Noah Lesslie.”

The fifth victim was 38-year-old James Lewis, who “was working at the home when the gunman opened fire, killing him.”

Apparently, a sixth person suffered a gun wound as well, but that individual survived and is being treated at the hospital.

On Thursday morning, Phillip Adams' body was found after a manhunt ensued. Police believe Adams took his own life by gunshot around midnight. According to TMZ, “there was a prior connection between Adams and the victims — the football player's parents live in the area and Phillip had reportedly been previously treated by Dr. Robert Lesslie.”

Phillip Adams' father spoke about the incident, obviously saddened by the news of his son. According to Adams' father, he “was a good kid” until “football messed him up.”

The only known connection between Adams and Dr. Robert Lesslie is that he had been a patient for Lesslie. It's still unclear as to why Adams lashed out and murdered Lesslie and his family. RIP to the victims of this horrific tragedy.

Phillip Adams was drafted by the San Francisco 49ers in the seventh round of the 2010 NFL Draft. He also spent time with the New England Patriots, Seattle Seahawks, Oakland Raiders, New York Jets and Atlanta Falcons.
