8 people found dead in three locations in the Chicago suburbs, Manhunt launched

The victims were found in three separate locations on Sunday and Monday, authorities told reporters Monday evening, hours after warning on social media that the man should be considered “armed and dangerous.”

Chicago: A man has shot and killed eight people at three locations in suburban Chicago since Sunday and remains at large, authorities said Monday. Police in Will County and the city of Joliet said they did not know a motive for the killings but said the man knew the victims. The FBI's Fugitive Task Force assisted local police in the search for the suspect, Joliet Police Chief William Evans said.

The victims were found in three different locations on Sunday and Monday, authorities told reporters Monday evening, hours after warning on social media that the man should be considered “armed and dangerous.”

One of the dead was found Sunday in a home in Will County. Seven others were found Monday in two homes in Joliet.

Authorities said they also believe another shooting in Joliet that injured a man on Sunday is related to the series of violence, but would not discuss their evidence. “I've been a police officer for 29 years and this is probably the worst crime scene I've ever been associated with,” Evans said Monday evening during a news conference outside the Joliet homes.

Will County Chief Deputy Dan Jungles said during the news conference that officers had staked out one of the homes since Sunday evening in case the suspect in that day's shooting returned to them. When no one showed up, officers finally went to the door of one of the houses. No one answered, so they tried the other house, which they knew was connected to the first house, and found the first bodies. Jungles provided no further details.

Jungles said he had no clues yet as to how long the people in the homes had been dead. He said autopsies are pending.

Evans said the victims found in the homes Monday were family members. When asked if the victims were members of the suspect's family, Jungles said he could not comment other than to say the suspect knew them.
