Chicago, Illinois (CNN) -- The four people found dead this week in a suburban Chicago home were the victims of a murder-suicide, a coroner said.
A man, a woman and two boys were found dead Wednesday in a house in Addison, Illinois, west of Chicago, according to the DuPage County coroner's office.
A statement from the coroner's office identified the four as Thomas Mangiantini, 48, his wife Elizabeth, 46, and the couple's two sons, Angelo, 12, and Thomas, 8.
Police received a 911 call from a woman at 6:30 a.m. CT Wednesday, according to CNN affiliate WGN-TV in Chicago. When officers arrived at the scene, they found a female dead downstairs in the house and the bodies of three males upstairs, according to WGN.
A spokesman for the Addison Police Department declined to give more information Friday.
