LOUISVILLE (WHAS11) -- LMPD is still in the middle of a fatal crash investigation that started hours ago.

Police say one person died after a firetruck and another car collided at the intersection of McCloskey and Algonquin, in the Algonquin neighborhood. It happened just before 9 a.m. Thursday.

Officers are trying to piece together what led up to this crash. With it happening at such a busy time of day, there were a lot of neighbors in the area and police say that is helping them in their investigation with those people giving their different accounts of what they saw and heard.

Many of them said they heard a very loud crash and some saying they also heard the sirens from the firetruck going down the street.

Police say details are still limited at this point, but they know the firetruck was traveling down Algonquin and had its sirens on for an emergency run. They say a green Mercury was stopped at McCloskey, but it's unclear what caused the car to move forward and collide with the firetruck.

One person died in the crash, but police aren't saying if that individual was in the car or a pedestrian. The four firefighters on the truck were taken to the hospital with minor injuries. Police say a female victim in the Mercury was also taken to the hospital, but there's no update on her condition.

Several witnesses who rushed to help that lady, said instinct just kicked in instantly.

"She was like, just help me, and I told her, ‘I'm not going anywhere.’ She wouldn't let my hands go."
Timothy Frierson, a witness, said. "It happened right in front of me. All I was doing this morning was trying to take my son to school, get back, and have some work done and here I am. It was horrendous, worst thing I've ever witnessed. "

The Public Integrity Unit is investigating this case, along with LMPD's traffic unit. That is standard protocol whenever there is a metro agency involved in a crash.

Witnesses said they want to commend the firefighters involved who jumped into action to try and help the victims even though they were hurt themselves.

There are just stop signs on the McCloskey side of the intersection, and that's something neighbors are already calling to change. They said drivers speed down this street constantly, and they want to see increased safety measures put in like stop lights and more stop signs.

Police expect the area to be closed for at least several more hours.
