Matt Sullivan was last seen, according to police, around 1:45 p.m., Friday at McAlpine Creek Park, an expansive park and greenway area off Monroe Road and Independence Boulevard in east Charlotte. Sullivan was reported missing after not coming home though he'd told his family he'd be back in a few hours, authorities said.
Sullivan is white, 6-feet-2-inches tall and weighs 220 to 225 pounds, police said. He has brown hair and blue eyes, a beard and mustache and is believed to be wearing teal shorts, according to CMPD.
Anyone who knows of Sullivan's whereabouts should immediately call 911, police said.
On Facebook, Sullivan's friends encouraged others to walk a trail in the park to help in the search. The 114-acre Mecklenburg County park has hiking and bike trails, a lake and fishing pier, soccer fields and a dog park.
