The DuPage County Sheriff's Office was conducting the investigation in the 2100-block of 63rd Street.
A source confirmed that a stabbing happened in the home and a suspect is in custody, the Daily Herald reports.
Neighbors said a woman and her two adult children live in the home.
"To have it be so close to home...it's really freaky," said Faith LaMantia, a neighbor.
No other information was made immediately available.
