A neighbor said Radcliffe Haughton sold cars for a suburban car dealership.
Before moving to Wisconsin, he would often stop by his parents' Wheeling home, where he was remembered as a nice guy.
It's been a few years since the Haughton family lived in Wheeling, but their former next door neighbor Richard Foster will never forget the family he calls great neighbors.
Foster remembers the son, Radcliff, as quiet well-mannered person.
"He taught my son how to play chess, we had block parties together and barbeques together," Foster said.
Foster says the Haughtons were Jamaican and he specifically recalls Radcliffe Haughton playing cricket matches in a big empty lot next to their home.
Sunday's tragedy comes as a shock to Foster. He says he never would have thought Haughton would be a suspect in a mass shooting.
"Everything we knew about out the norm but things change over the years," he said.
According to Haughton's Facebook page, he is a 1985 graduate of Wheeling High School. Foster said after working at a suburban car dealership, Haughton and his wife moved up to Milwaukee with their daughter.
While a domestic abuse temporary restraining order was issued against Haughton a few days ago, his father says he never expected anything like this to happen.
Radcliff Haughton Sr. said over the phone from Florida that knew about the court order against his son, however he would not answer any questions about it.
"I want to apologize to the people of Milwaukee who have been hurt, to all of those who are going through this traumatic experience," Haughton, Sr. said.
While Haughton, Sr. called his son a good guy, it's being reported that court records in Wisconsin and Cook County paint a different picture.
According to the Chicago Tribune, Haughton was charged with battery multiple times, but he was either found not guilty or charges were dismissed.
