Police are looking for a man they said stabbed his 11-month-old son and tossed him out of a car on Wednesday night.The child, Devon Chandler, underwent surgery at a hospital Thursday morning. His condition was described as stable, 6News' Jack Rinehart reported.Police said the boy's father, Kevin Chandler (pictured, right), 30, was with Devon, Devon's mother and a 5-year-old child at the Hermitage apartments, in the 2300 block of Hermitage Court. The mother told police that they were in a car when she remembered she didn't have a child safety seat.The mother, Angela Limbrock, said she handed Devon to Chandler, who was sitting in the back seat. The other child then said that Chandler had a knife, Limbrock said."I turned around and looked. I saw the knife up over him, so I started screaming, 'No,'" Limbrock told 6News. "As I was opening the door, he tossed the baby out of my vehicle. I grabbed the baby and realized that he had a knife in his back."Limbrock said Chandler drove the car away. The car was found at about 3:30 a.m. at the apartment complex.Limbrock said she went to a neighbor's apartment for help. The knife was still in Devon's back when he arrived at a hospital, police said."He was conscious, but the knife was buried all the way to the handle," Speedway police Detective Jim Thiele said.Chandler is about 6 feet tall and weighs 170 pounds. Police asked anyone with information to call Speedway police at 317-244-9543 or Crime Stoppers of Central Indiana at 317-262-8477.An arrest warrant for Chandler was issued on Thursday."We're still trying to determine motive here, but at this point I have no reason to believe he did this to get back at the mother or anything," Thiele said.Thiele said Chandler is homeless and had been staying with some friends or family. Chandler has been arrested several times on charges including domestic battery, auto theft and driving while intoxicated, records show. He served time in an Indiana prison for cocaine possession and carrying an unlicensed firearm near school property, records show. In 2005, police arrested Chandler after he allegedly kicked Limbrock in the head and body.
