Police in Chicago are investigating a horrific crime scene after discovering six members of a Mexican family — including two young children — brutally murdered inside their home. Officers described the scene as a “sea of blood,” with the victims found lying on the floor in multiple rooms. The motive behind the massacre remains unknown, and authorities say the case has left even seasoned investigators shaken.

Neighbors reported hearing loud noises before police arrived but said the family had never shown signs of trouble. The sole survivor, a father who was not home at the time of the killings, is said to be in shock as detectives work to piece together what happened.

Earlier today, police confirmed that an additional body connected to the case was found at an undisclosed location. The identity of this individual has not yet been released, and officials are investigating whether it is related to the Chicago murders.

Law enforcement has increased patrols in the area while urging anyone with information to come forward. Authorities have called this “one of the most disturbing crimes in recent memory,” as the community mourns and waits for answers in a case that has left one father alone — and a city in disbelief.
