Three people are dead, including the suspect, following a shooting in front of a middle school in Berwyn on Tuesday afternoon.

The shooting sent over 100 kids inside into a hard lockdown.

Authorities have been investigating for hours outside Lincoln Middle School in the 6400 block of 16th Street. Roads remained closed off for blocks as investigators continued to process the scene.

The shooting happened shortly after 4 p.m. when students were still inside for after-school programs. Officers happened to be nearby when they heard gunshots and responded. Around 20 shots rang out.

Two dark sedans rammed into each other, with some windows blown out and bullet holes in the windshield.

Orlando Valentin, who lives down the street from where the incident occurred, said he heard the gunshots.

"I was pulling up and I hear the gunshots, and they sounded like fireworks at first," he said. "Then, some guy was telling me not to keep going. So, I made a left in the alley, and there were these kids running around."

Valentin said the kids were frightened. He went over to the scene and saw the aftermath.

"I walk that way and then I see a guy slumped over in his car," he said.

Berwyn police said officers saw a man shooting a rifle into another car. As officers approached, they said the man opened fire at them. They took cover and did not shoot back.

Division Commander Michael Fellows said the shooter appeared to have died from a self-inflicted gunshot wound.

Three people died in what police called a domestic-related shooting.

A teacher, who did not want to be identified, said he was coaching cross country when they went into lockdown. He said the students asked him what happened, and at that point, they had no idea since they did not hear the gunshots. 

Mike Franco lives a few doors down and is still taken aback that this happened right outside the middle school he grew up next to and attended.

"Hopefully this is just a small incident and we don't see anything like this ever again," He said.

Lincoln Middle School will be closed on Wednesday. The school said students are encouraged to come to school if they need to talk about the incident, as social workers and counselors will be available.

The police said there is no danger to the public and are investigating the shooting as an isolated incident.

Residents are being advised to stay vigilant and report any suspicious activity to the police.
