The two and a half month-old baby was found unresponsive inside the apartment with 9 other people, including the child's teenage mother, in the 3100 block of West Ainslie in Chicago's Albany Park neighborhood.
Neighbors say he was unresponsive when police arrived. There were several people living in this small apartment including 10 children living in filthy conditions. Neighbors describe the apartment as dirty with the floor covered with debris.
Despite the living conditions, it's not clear how the baby, Ivan Carlos, died.
"I still find it hard to believe because it wasn't sick or anything. I don't know why," said Virginia Bowers, neighbor.
"I'm sad for her. She lost her baby," said Chris Gibens, family friend.
"All they could tell us was that the baby had passed away. And I know that the baby was healthy and had no problems," said Yasmin Sanchez, family friend.
Zadie Real Estate which manages the building told ABC7 that apparently only four people were supposed to be living in the apartment. The real estate company said the apartment was always filthy and they had problems with the family members and the family was scheduled to be evicted January 31.
Sources tell ABC7 news that DCFS had prior contact with the baby's mother and grandmother.
An autopsy is scheduled for Wednesday.
