South Bend police have issued an arrest warrant for 29-year-old Kenny Lee.
He is accused of shooting his 6-year-old son, who witnesses say was not the intended target.
A family member Friday spoke with WSBT and said the boy is going to be okay.
His leg is broken and is in a cast, but he did not require surgery.
Investigators say the boy was not the target, his uncle, Jerome Holloway, was.
Holloway says he took his great niece and nephews trick-or-treating at a nearby church, and when he got home, Lee was there to visit.
The men got into a fight.
"I was just informing him that he needs to take care of his kids, that's all I said", explained Holloway.
Holloway said he repeatedly told Lee he needed to be more involved with the three children he shares with Holloway's niece. Then Lee got mad and pulled out a gun in the house, which is located on North Olive Street near Prast Street.
"He hit me on the head with the gun," said Holloway as he displayed a bump on his head.
Holloway said his niece told the men to stop arguing and asked Lee to leave, but the argument continued outside, and according to the police repor, as Lee was getting on his bicycle, he turned and fired a shot.
"I come to the end of that fence; he pulls the gun out, and he shoots," said Holloway.
"When did you realize your nephew was hit," asked WSBT reporter Denise Bohn.
"My niece started hollering, and I didn't know what was going on," responded Holloway.
Blood stains from the boy's injury were on the steps and front porch and on a couch inside the home.
"He is okay...going to be fine," said a cousin, who did not want her name released.
"He is lucky the bullet missed two arteries in his leg," she added.
The family says they don't even know if Lee realizes he shot his son.
They are hoping he turns himself in.
Police say Lee has a criminal record but no history of violent crimes.
He is wanted on charges on Attempted Battery and Criminal Recklessness.
Despite being on the run, formal charges were filed against him on Friday, and bond was set at $60,000.
