A Glenwood man is suspected of killing his wife and adult son, then cutting his own wrists as he waited for police to arrive, according to authorities in the south suburb.



Responding to a 911 call from the man, police said they found Delphenia Williams, 68, and Irven Williams, 33, dead on the second floor of the home in the 800 block of East 194th Street around 3:30 p.m. Thursday, according to Glenwood Police Chief Demitrous Cook.



Officers found the man in the garage with apparently self-inflicted cuts to his wrists, Cook said. He was taken to a hospital and his injuries were not believed to be life-threatening.



"It's a tragedy,'' Cook said. "A man called the dispatch center and said he killed his son and wife. We have no idea at this time of the motive or how they were actually killed."



Both the mother and the son were pronounced dead at the scene, according to the Cook County medical examiner's office. Both had lived in the home.



The last murder in Glenwood nine or 10 years ago, police said.
