ROCKFORD, Ill. (WTVO) — Rockford Police said four people, including a mail carrier, are dead and seven injured after a series of attacks by a suspect in a southeast neighborhood Wednesday afternoon.

Police announced that they took a 22-year-old male suspect into custody at 1:35 p.m. after 11 people were attacked in a bloody rampage through a Rockford neighborhood.

Police said the four deceased victims were a 15-year-old female, a 63-year-old female, a 49-year-old male and a 22-year-old female.

Authorities initially responded to a 911 call in the 2300 block of Holmes Street around 1:15 p.m.

Winnebago County Sheriff Gary Caruana said the suspect was involved in a home invasion on Florence Street. A female victim is receiving treatment for stab wounds. Caruana also said a good Samaritan who intervened in the attack is also receiving medical care.

The suspect then reportedly continued attacking people throughout the neighborhood, including the 2100 block of Eggleston Road and the 4800 block of Cleveland Avenue. The area is located between between Charles Street and Harrison Avenue, east of N. Alpine Road.

At a press conference Wednesday afternoon, Rockford Police Chief Carla Redd said four people are dead, one is in critical condition, and four others are hospitalized in stable condition.

Redd said not all of the victims were stabbed, and said there was no known motive for the crimes.

Rockford Mayor Tom McNamara released a statement following the attack, saying, “Today, we are shocked by another horrific act of violence against innocent members of our community. We can report that the suspect is in custody and the threat has been neutralized. Now that he is in custody, our primary concern is ensuring that our community members directly impacted by this violence are supported throughout their healing and recovery. We are working with community partners to provide support and services quickly and conveniently to those residents. We will announce those details soon.

“We have multiple jurisdictions working on multiple crime scenes to develop an understanding of what transpired in an effort to prevent this from happening again. We will continue to provide updates,” McNamara said.

The City of Rockford said emotional support and counseling services will be offered free of charge at Flinn Middle School, at 2525 Ohio Pkwy, beginning at 9 a.m. on Thursday.

Rep. Dave Vella (D-Rockford) issued a statement, saying, “

“I am heartbroken by the actions of the perpetrator of these horrible stabbings in Rockford today. These victims deserve to be safe and secure in their homes from violence that they didn’t ask for and don’t deserve. They need our support now and my office is ready and willing to do what we can to help. I am committed to working closely with Mayor McNamara and other authorities to help these neighbors of ours to address this senseless violence and ensure that justice is served.”
