FOG BLOG SPORTS LOG: EX NFLer , PHILLIP ADAMS KILLS 5 THEN HIMSELF, INCLUDING WIFE AND GRANDKIDS!

ROCK HILL, S.C. -- Former NFL player Phillip Adams fatally shot five people, including a prominent doctor, his wife and their two grandchildren, before later killing himself, authorities said Thursday.

York County Sheriff Kevin Tolson told a news conference Thursday that investigators had not yet determined a motive in the mass shooting Wednesday.

"There's nothing right now that makes sense to any of us," Tolson said.

Dr. Robert Lesslie, 70, and his wife, Barbara, 69, were pronounced dead at the scene Wednesday, along with their grandchildren Adah Lesslie, 9, and Noah Lesslie, 5.

A man who had been working at the home, James Lewis, 38, from Gaston, was found shot to death outside, and a sixth person was hospitalized with "serious gunshot wounds," York County Sheriff's Office's spokesperson Trent Faris said.

At Thursday's news conference, Tolson played audio of two 911 calls related to the shooting, the first from an HVAC company that employed Lewis and the other person doing work at the Lesslie home. One of them, the caller said, had called him "screaming'' and saying that he had been shot, and that his co-worker was shot and "unresponsive.''
