Police have identified the suspect as Keewon Taylor, 20.
There has been no sign of Taylor since about 11:30 a.m. when a home invasion allegedly took place in Streamwood. Police say Taylor took a man -- with whom police say he is acquainted -- from his Streamwood home at gunpoint and ordered him to drive that victim's car to an undisclosed location. They never got there, however, because the victim fought the gunman off. He crashed his own car, and the gunman then ran off into a wooded, industrial-type area.
Police responded very quickly with a massive search from a number of departments. They used police dogs as well as a helicopter.
"The victim was targeted in this case. We don't think this was a random act of violence," said Chief Jim Keegan,Streamwood Police Department.
Policerecovered a shotgun they believe is the weapon that Taylor had been carrying and a bag of ammunition. They don't know whether he has another weapon.
Police say they have already been to Taylor's house. He is described as in his early 20s, a light-skinned African-American, wearing a red sweatshirt with a white stripe, and blue jeans.
Earlier in the day, the Tefft Middle School and Heritage Elementary School were put on lockdown as a precaution, and parents were called to come get students at the end of the school day.
"Anytime you close down schools and libraries and roads, I mean, we apologize for the inconvenience, but of paramount concern, of course, is the public, especially school children," said Streamwood Deputy Police Chief Jim Keegan. "And we thought we took necessary precautions and steps to keep our community and our kids safe."
About eight different schools were on soft lockdown for a while. Eventually, they were able to just restrict that to two of them -- Tefft and Heritage. Students who walk to school were being held until parents could come pick them up. Some students were given rides home by police officers.
