The Jacksonville Sheriff's Office says 42-year-old William C. "Chris" Pettry died early Sunday inside Fionn MacCool's, an Irish-themed restaurant at The Jacksonville Landing.
Twenty-seven-year-old Matthew Hinson is being held without bond on a murder charge. Jacksonville Jail records didn't list an attorney for Hinson.
A news release issued by the sheriff's office on Monday says witnesses told detectives that Hinson cut Pettry's throat, put the bloody knife in his pocket and calmly walked out of the restaurant.
Pettry lived in Lake Villa, Ill., about 50 miles from Chicago.
Pettry's cousin, Quincy Asbury Jr., told The Chicago Tribune that Pettry flew to Florida on Friday to go to the Bears-Jaguars game.
