A man stabbed his 11-month-old son in the back, threw the boy out the car window with the kitchen knife stuck in his back and then drove away, police said Thursday.

"He was conscious, but the knife was buried all the way to the handle," said Speedway Detective Jim Thiele. The boy, Devon Chandler, was in stable condition at a hospital Thursday.

"To the amazement of the doctors and everyone else involved, (the knife) somehow managed to just miss the vital organs," Thiele said.

Police have enlisted the FBI's help in locating the father, 30-year-old Kevin Chandler, who was charged with attempted murder.

Police think 30-year-old Chandler and the boy's mother, Angela Limbrock, were arguing as they prepared to leave Limbrock's apartment on the west side of Indianapolis Wednesday night.

Limbrock handed Devon to Chandler so she could retrieve his car seat inside the home. As she left the car, she heard Chandler swear at the boy and turned around to see him throw Devon out of the car window, according to a police report. When Limbrock picked up her son, she saw a knife in his back, the report said.

She ran back to the home, where residents called for an ambulance.

"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," the detective said.

Chandler, who was sitting in the back seat along with a 5-year-old boy, drove away. The boy was able to get out of the car before Chandler drove off, Thiele said.

Chandler has been arrested several times for crimes 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.
