Campbell's death is Lexington's 14th homicide in 2013, Lexington police spokeswoman Sherelle Roberts said. There were a total of 15 homicides in 2012, she said.
The stabbing in the 1900 block of Mark Avenue occurred about 10 p.m. Wednesday, during a fight involving at least three people. Mark Avenue is in a neighborhood off Georgetown Road.
Coroner's officials said in a news release that Campbell died at University of Kentucky Chandler Hospital of a stab wound to the chest.
Steven Campbell's father, Steve Campbell, said he didn't know details, but he thought his son had gone to the aid of a friend who was concerned that he was about to become involved in a fight.
"He was a caring person," Steve Campbell said of his son.
Funeral arrangements were pending Thursday at Kerr Brothers on Main Street, Parker said.
A fund in Campbell's name has been created at Woodforest National Bank in Lexington to help with funeral expenses, Parker said.
