A 19-year-old Oak Lawn man faces a first-degree murder charge in the stabbing death of his mother that occurred on Saturday in the home they shared in the 4600 block of West 106th Place.
Oak Lawn police said they responded to a domestic disturbance call involving someone with a knife at 4:52 a.m. Saturday. Upon arrival, they said Grace V. Sink, 50, who made the 911 call, told them she had been stabbed by her son, William, during a physical altercation. She was transported to Advocate Christ Medical Center for treatment of stab wounds, and survived emergency surgery. But she died about 9:30 a.m. that day. An autopsy determined that she died as a result of multiple sharp force injuries, according to the Cook County Medical Examiner’s office.
Police said William Sink was at the home when they arrived and he also was taken by ambulance to the hospital. He remained there this week receiving psychiatric treatment. Following an investigation by Oak Lawn Police and the South Suburban Major Crimes Task Force, the Cook County state’s attorney’s office filed the first-degree murder charge against Sink on Sunday.
Judge Patrick Rogers issued a $2 million bond for William Sink on Monday, after prosecutors made an appearance in his Bridgeview courtroom to outline their case. Sink, a 2016 graduate of St. Rita High School, was represented by his attorney, Dave Fewkes. His father, who is a Chicago police officer, also was in the courtroom, according to reports.
Sink, who played hockey at St. Rita, was currently attending Moraine Valley Community College. Rogers ordered that he be transferred to Cermak Health Services of Cook County if he could not post bond. He is next scheduled to appear in court on Nov. 17.
Prosecutors are alleging that Sink stabbed his mother about 5 a.m. Saturday inside their home after arguing and fighting with her, his younger brother, and his mother’s boyfriend earlier. The other two males separated him from his mother and the three went outside, where he allegedly knocked the boyfriend unconscious. Sink then returned to the house and resumed fighting with his mother.
“The entire community is really saddened and shocked to hear about this. Our hearts go out to the Sink family,” said Oak Lawn Mayor Sandra Bury on Tuesday.
“I really want to thank the first responders and the staff of Advocate Christ Medical Center for doing all they could for her,” said the mayor.
“It is just awful, a real tragedy for a whole family that has been torn apart. You have a mother’s life taken, a young man with a promising future that is now gone, and his brother and father (in mourning).”
“I don’t know what the exact circumstances were in this case, but we have got to make mental health a priority,” she concluded.
