The shooting happened around 7:30 a.m. Thursday in the 300 block of Elmhurst, which is near Chicago Boulevard and the John C. Lodge Freeway.
"He looked out for everybody. If he wasn't there today, me and my mom would be dead," says a daughter of the victim, who did not wish to give her name. She says the gunman ran up on the porch and shot her father multiple times, then pointed the gun at her and her mother before hopping in a getaway car.
She believes the shooting stemmed from a long-running feud with neighbors. She claims they've even shot her before, though police cannot confirm any previous incidents at the home at this time.
Police are now looking for 25-year-old Dimarco Hoskins, who was at the home at the time of the shooting. Police are not saying he was the shooter, but do say he ran away from the scene.
"The person who saw the shooting ... gave us this information about the person that was over there. Now, we want to ask him some questions, and maybe we'll put all the facts together about the vehicle and why did he flee the scene," says Highland Park Police Chief Kevin Coney.
The victim's family also wants answers and arrests. That's loved one, Brandon Rice, is a father to six and a grandfather to three.
"If he wouldn't have been outside, me and my mom would be dead in the street," says one of his daughters.
Hoskins is described as being about 6 feet tall and weighing around 160 pounds. Police do not have a description of the vehicle he was last seen it.
If you have any information about Hoskins or this crime, you're asked to call the Highland Park Police Department.
