A suburban Chicago man has been found guilty of stabbing his 3-year-old son to death and sexually assaulting the child's mother in a 2011 attack at her home.
Thirty-year-old Gregory Sandifer of Homewood was convicted Tuesday in a bench trial in Cook County Circuit Court.
The attack took place at his girlfriend's apartment on the West Side of Chicago.
According to prosecutors, the couple was arguing when Sandifer sexually assaulted the woman at knife point. Authorities say he stabbed her four times and pushed her out of a window. She survived and was able to flag down a passing policeman.
But Sandifer fatally stabbed their son before the officer could enter the apartment.
Sandifer is to be sentenced next month, and faces up to life in prison.
