Capt. Dave Bursten, a spokesman for the Indiana State Police, told NBC News Makowski is a 19-year veteran of the force.
"We are all concerned for his welfare and are just hoping and praying for his recovery," Bursten said.
The Tribune reported that the night of the shooting was not the first time police were called to the family's home. Officers were sent to the house Feb. 13 for a welfare check after Makowski's son called 911.
The boy told the officers he had "been bad" and was hit by his mother, the Tribune reported. No report was filed by the officers.
The 11-year-old was also named in a police report from September regarding the alleged battery of an 8-year-old neighbor. His alleged involvement in the battery is unknown, due to Indiana confidentiality laws regarding minors, and it was unclear how badly the younger boy was injured, the Tribune reported.
Makowski’s son is being held in juvenile custody.
