4 dead, 1 in critical condition after Illinois stabbings; suspect in custody

An adult male allegedly stabbed multiple victims in the Rockford, Illinois area on Wednesday, leaving four people dead, one in critical condition and four others in stable condition, authorities said in a press conference Wednesday.

A postal worker is among the four individuals who died, Rockford Police confirmed.

Late Wednesday night, police said in a release that the deceased included a 15-year-old female, a 63-year-old female, a 49-year-old male and a 22-year-old male.

Rockford police said the suspect, who is 22, was taken into custody at 1:35 p.m. There is no known motive at this time.

The attacks took place before 1:15 p.m., local time, near Holmes Street, Cleveland Avenue and Eggleston Road, according to authorities, who noted this was a "multi-jurisdictional crime scene."

Winnebago County Sheriff Gary Caruana said there was a home invasion near the intersection of Florence and Eggleston Road. A young woman who fled from the residence with stab wounds in her hands and face is in critical condition, Caruana said. He added that she is currently intubated.

A "Good Samaritan" who stopped to help the woman was also allegedly stabbed by the suspect, Caruana said, but that individual is among those in stable condition.

"Words can't even express my thoughts right now; this a pretty painstaking event," Rockford Police Chief Carla Redd said, adding, "This was a heinous crime."

Redd noted that not all of the victims were stabbed in the string of attacks, and there were no gunshot victims.
