Another person was wounded in the incident, which happened late Monday night on Hacker Drive near Caton Farm.
Police do not have a motive or suspect for the deadly shooting.
Juan Gonzalez's next door neighbors, Bill and Joan Mitschke, say the 39-year-old Lockport Township resident was hanging out with a friend in his family's garage when both men were shot around 9:30 p.m. Gonzalez was killed.
"There was a woman and child home home," said Deputy Chief Ken Kaupas, Will County Sheriff's Office. "So this could have been a lot worse."
The Will County Sheriff's Office is in charge of the investigation. On Tuesday, police canvassed the home and the family's vehicles for evidence Tuesday. While they don't have good descriptions, they believe they are looking for two men.
Police say residents don't need to worry.
"There doesn't seem to be a randomness to this," Deputy Chief Kaupas. "They may have been some knowledge, there may have been some contact between our victims and the shooters, or so the investigation seems to be going in that direction."
Kaupas says that nobody seems to know why Gonzalez, a long-time contractor for a Romeoville company, would be targeted. His neighbors agree.
"We can't see any reason why Juan would be targeted," said Bill Mitschke. "He's a very nice guy, hardworking, close to his family. And we don't know anything about the other person in the garage that was injured."
"It's just a little postage stamp in the middle of nowhere, and everybody knows everybody in the neighborhood," said Jerry Shepich, neighbor.
The second man shot is still hospitalized in stable condition. A relative of his says it appears he'll recover.
Gonzalez's colleagues tell ABC7 several of them were so distraught they went home after hearing the news Tuesday morning.
No arrests have been made.
