One can only hope he resists arrest:

INDIANAPOLIS — A man accused of stabbing his 11-month-old son in the back, then throwing the wounded boy out the window of a parked car was still on the loose Thursday, a day after the stabbing, police said.
The kitchen knife was still in Devin Chandler’s’s back Wednesday night when he was rushed to a hospital for treatment, according to Speedway Police. The boy was listed in stable condition at Riley Hospital for Children Thursday.
“He was conscious, but the knife was buried all the way to the handle,” Speedway Detective Jim Thiele said. Police were still searching for the father, Kevin Chandler, 31, on Thursday.
