McKinney father accused of killing 9-year-old dies in jail

The McKinney man who was accused of murdering his 9-year-old son last year died while in police custody.

According to the Collin County Sheriff’s Office, Ponnazhakan Subramanian attempted suicide by hanging in his jail cell in early December.

He was rushed to a McKinney hospital and died there about a month later on Jan. 20.

Police said Subramanian fatally stabbed his son, Nanitin Ponnazhakan, in January of 2023.

His wife later found their son unconscious and bleeding in the garage. She ran to a neighbor’s home for help.

Officers then forced their way into the house and found Subramanian hurting himself with a knife.
