CHICAGO (WBBM NEWSRADIO) -- A person was found dead Saturday afternoon in southwest suburban Oak Lawn after police responded to what they initially described as a barricade situation.
About 8:20 a.m., officers arrived to the 10400 block of South Mason Avenue after receiving a call from someone saying they were concerned a family member may hurt himself or others, according to Oak Lawn police.
When they arrived, officers and a witness heard what sounded like a gunshot come from inside a residence, police said.
An autopsy was scheduled for Sunday at the Cook County medical examiner’s office.
Police initially thought they were dealing with a “barricade situation,” warning residents in a tweet about 10:30 a.m. to stay indoors as units investigated a barricaded subject.
They tweeted that the situation was under control around 2:30 p.m., about four hours later.
Mason Avenue was expected to remain closed between 104th and 105th streets into the evening.
