Police said one person was killed and three others were hurt in a crash that involved five vehicles, including a dump truck, Tuesday morning.
Investigators said the accident happened on 2nd Avenue near the Hot Metal Bridge in Pittsburgh's South Side.
Jake Stevens told Channel 11 News he was near the crash, and just missed being hit.
“It just looked like it hit him. It hit the one car and that car flipped into a couple of others. As other cars were trying to swerve out of the way, they collided with each other,” Stevens said.
Authorities said nine crash investigators were brought in to investigate.
“We definitely know who the at-fault driver is in this particular case. It’s just a matter of five vehicles banging off each other like a big puzzle. We have to put the puzzle back together,” Collision Investigation Unit Sgt. Daniel Connolly said.
Connolly didn’t say which driver was to blame because criminal charges are likely to be filed.
“We are looking at possible speed and passing issues, and we are probably going to be looking at charges in this particular case,” Connolly said.
Crews worked for hours to clear the scene, and the road eventually reopened Tuesday afternoon.
