GLENVIEW, Ill. - "I am a murderer," a man with blood on his clothes and hands told Glenview police, after fatally stabbing his father over an argument about marijuana at their home on Monday, prosecutors said.

Isaac Thurston, 20, also said, "I don’t know why I did it," and described the argument that led to him attacking his father, Perron Thurston, 50, according to a bond proffer prepared by Cook County prosecutors.

Father and son began arguing about 6:30 a.m. at their home in the 1100 block of Arbor Lane when the elder Thurston became upset with his son, who had smoked marijuana before heading to work at a coffee shop.

Perron Thurston didn’t think his son could work in that condition, so he called the coffee shop and told them that Isaac wouldn’t be coming to work, the proffer states.
