Horror as knifeman, 22, goes on 20-minute bloody rampage in suburban Illinois killing four people including teen girl, 15, and mailman and injuring seven more in terrifying attack that kicked off with a burglary

Four people are dead, including a 15-year-old girl and a 49-year-old mailman, after a deranged knifeman went on a brutal rampage through a sleepy Illinois suburb on Wednesday afternoon. 

A 22-year-old man is in custody in relation to the crime. He has not been identified nor has a motive been released publicly for the horrific attacks. 

Police in Rockford, Illinois, 90 miles west of Chicago, responded to a series of locations at 1:14pm after receiving calls about a burglary. From there, a manhunt began resulting in the suspect being arrested in the vicinity at 1:35pm.

One victim, who survived, was stabbed in the face as she tried to escape the deranged attacker who was described as being 'very bloody' and resisting when he was hauled away.

The victims have so far only been identified as two women, ages 15 and 63, and two men, aged 49 and 22. Three of the victims were pronounced dead at the scene, one died later at a local hospital. 

 Five other people were rushed to local hospitals to be treated for injuries, four were released as one person is still being treated in serious condition.

'We are reeling as a community from another senseless act of violence,' Rockford Mayor Tom McNamara told the media in the aftermath of the tragedy. 

One local, Eric Patterson, told the Rockford Register Star that he saw two teenagers bloodied from an attack and a middle aged woman being taken away in an ambulance. 

Patterson said that the mailman was run over by a pick up truck. Rockford Police Chief Carla Redd earlier confirmed that not all of the victims were stabbed but none were a shot

'We don’t have a clear motive in regard to what caused this individual to commit such heinous crimes,' the chief added.  

Winnebago County Sheriff Gary Caruana told the media that one of the victims was stabbed as they tried to stop the attacker from fleeing the area. That person is not among those killed. 

'She young lady ran from him. She got some stab wounds in her hands and in her face. She is currently at a hospital, and she is intubated. She is in serious condition,' he said.  

Caruana said another of the victims was a 'young female' who ran from a home that the attacker broke into. 

Vanessa Hy, who lives in the community, described the scene when the cops descended on the sleepy town. 

'All of a sudden, we heard police run up on both sides of the house screaming: "Stop! Get down!" Then they ran into the backyard and after a few minutes we saw them bringing the suspect down the driveway in handcuffs and he was very bloody,' Hy told WREX-TV. 

'It makes no sense. t’s almost like playing a video game, but it's reality. It makes no sense. It’s like Grand Theft Auto. I'm going to run over the mailman here,' Patterson said.

'I'm going to stab a couple people there. I am going to go in this house over here. It’s not making sense. You can’t rationalize this,' he added. 

Another resident, Cassandra Hernandez, paid tribute to their mail man calling him a 'very good man.' 

Resident Ruth Gallagher called the mailman 'the kindest person' in an interview with CBS Chicago. 

'He would help anybody; would step in and help - always friendly. We will miss him,' she added.  

'It’s hard to grasp how this could happen and how emotional and raw the community is tonight. As a dad, a son, a husband, the Mayor and a Rockford supporter, my heart is breaking for those who have lost their lives, their families and our community,' the mayor said in a Facebook post.  

Redd said residents in the area were being asked to review their home surveillance camera footage for anything related to the attacks.

Rockford’s population is about 150,000 and it’s 90 miles (145 kilometers) miles northwest of Chicago. The violence Wednesday came days after a teenage employee of a Walmart in Rockford was stabbed and killed inside the store.
