Mt. Prospect man commits suicide in Cook County jail

A Mount Prospect man accused of stabbing his brother earlier this summer committed suicide at Cook County jail over the weekend, officials said.

Robert Jastrebski, 55, was pronounced dead at 3:51 a.m. Saturday at the jail, and an autopsy on Sunday ruled the death a suicide by hanging, according to the Cook County medical examiner’s office. He hung himself with a bedsheet and his cellmates alerted the guards as soon as they woke up and noticed, said sheriff’s spokesman Ben Breit.

Jastrebski was charged with aggravated battery with a deadly weapon after a fight with his brother on June 29. His brother, a 59-year-old man from Chicago, told police Jastrebski stabbed him in the abdomen and hand with a steak knife, police said. The victim refused medical treatment for his injuries, which police said were not life-threatening.
