Reports of gunshots at the Brighton Park home were called into authorities at 10:45 a.m. Monday. Officers reporting to the scene forced their way into the home in the 2700-block of West Pope John Paul II Drive. Inside, they found the wounded children and the dead officer, 29-year-old Dannie Marchan. Police said the officer, who worked in the 7th District, shot himself.
The children were taken to Mt. Sinai Hospital, where the girl was pronounced dead Monday afternoon. Their mother was not home at the time of the shooting.
"It was a lot of police running and detectives. There was a lot of noise. Later on I hear two shots and the people with the ambulance have two kids," said Adela Lozano
Authorities called the shooting a domestic situation. Originally, there were reports of a standoff, which led nearby Shields Elementary School to go into lockdown while police worked the scene.
"As soon as the calls came out the schools in the area were notified," said Cmdr. Gene Roy Chicago Police Department. "We were in constant communication."
That school then became a haven for authorities shocked by the actions of their fellow officer. A parish priest and counselors gathered there to help officers cope.
The Independent Police Review Authority is also investigating.
"An officer had fired the weapon. That brings us to all police shootings. An officer fires a weapon, that's when we come to the scene," said Mark Payne, Independent Police Review Authority
