Donald Leo McNamara, an 86-year-old man from Chicago, was found shot to death in his Canaryville home on August 11, 2017. The Cook County medical examiner ruled the wound to the head a homicide.

Authorities charged his 58-year-old son, Donald J. McNamara, with first-degree murder. Police say the shooting followed a heated argument over family issues after the father allegedly refused to apologize for making disrespectful comments about the family; the son reportedly confessed to killing his father because of the insults. The son was denied bail and his defense raised serious mental health issues and medication use, while the court described him as a danger to the community.

The case centers on a long-standing, strained father‑son relationship that culminated in lethal violence. If anyone knew Donald Leo McNamara or has information about the events in Canaryville on August 11, 2017, please share what can help the investigation.
