Chicago police say there are "inconsistencies" in a man's claims that he shot and killed three people after they broke into his home on the Southeast Side over the weekend.



The man, in his 30s, was taken in for questioning after officers responded to a 911 call around 5:30 p.m. Sunday and found a teenage boy, a woman and a man dead from gunshot wounds inside the home in the 10200 block of South Ewing Avenue, police said.



He was later released, but police said they are still trying to get answers to their questions through an attorney the man has hired.



"We noticed inconsistencies in the initial version of events that was told to detectives, as well as with the crime scene," chief police spokesman Anthony Guglielmi said.



"I can't get into specifics as to what those are, given there is an ongoing interrogation," he added. "But the homeowner has now retained counsel, and we are working with his attorney to get our questions answered."



The man told police that the three entered his home through the basement. He said he shot them, then locked himself in his bedroom, according to police.



Responding officers found 17-year-old Antonio Lopez, 22-year-old Narcisco Ledesma and 24-year-old Celeste Cockriel dead of gunshot wounds, police said.



Ledesma was shot in the head, and Lopez suffered multiple gunshot wounds, according to the Cook County medical examiner's office.



Police have said the man at the home has a valid firearm owner's identification card.
