A 20-year-old is dead and another person was hospitalized after their vehicle slammed into a Milwaukee Department of Public Works vehicle Thursday morning. 

The crash happened around 9:40 a.m. at the intersection of West Sheridan Avenue and North 76th Street. 

A public works truck pulling a wood-chipper was crossing Sheridan Avenue when a Gold Buick came over a hill and slammed into the truck broadside, according to a press release.

Witnesses said they saw the Buick moments before the crash. 

"He had ran the light down there and he was coming this way. And she said he was driving in disarray when he ran the light," Arlene Cobins, who was driving in the area when it happened, said.

"I guess they must of didn't know it and they ran right up into up under it and got stuck," Robert Quinn, a neighbor to the scene, said.

Neighbors told CBS 58 News that speeding is a definite problem on North 76th Street but witnesses said there may have also been some sort of conflict happening in the car before the crash.

"She looked concerned," Cobins said of the female passenger who died in the crash. "Uh huh. As he ran the red light down there. She said the passenger looked concerned. And that was it."

Authorities are continuing their crash investigation. They have not said yet what may have lead to this situation.
