Suspect being questioned in connection to Joliet Halloween mass shooting that killed 2, inured several others

JOLIET TOWNSHIP, Ill. - A suspect is being questioned in connection to the Joliet Halloween shooting that left two people dead and several others injured. 

The 18-year-old from Joliet, Joskar Sebastian Ramos, is currently charged with aggravated unlawful use of a weapon, obstructing justice and illegal possession of ammunition. At this time, however, he does not face any charges related to the Halloween shooting, police said.

He had an active Will County warrant on unrelated weapons offenses that occurred while he was a juvenile, the Will County Sheriff's Office said.

Deputies set up a perimeter of his residence around 9:45 a.m. and attempted to serve the warrant. They announced their presence several times while outside the home, police said.

They then observed the suspect look out of a second story window and then disappear from view.

As the deputies continued to attempt to have the suspect come to the door, one deputy observed a gun that had been placed outside of the window onto the roof of the first floor, police said.

Detectives then forced entry into the residence. Upon doing so, police said he began to respond and followed commands.

He was taken into custody.
