A shocking discovery of human remains in a suitcase was made along the side of the road on the border of Huntington and Huntington Station Tuesday.

Suffolk police say the body was found in the suitcase around noon outside of an apartment building.

Investigators were back at the apartment building Wednesday evening.

Neighbors tell News 12 that they were at a building located on 320 Nassau Road, which is near the location where the human remains were found in a suitcase.

One resident, who asked to be referred to as Taylor, says she noticed something unsettling during a morning walk and called police.

"I was taking a walk and I just, I smelled something. I saw a whole bunch of flies. I had looked over and I saw the suitcase,” she said. “So then I called it in, I was like I'd rather be safe than sorry. This is out of the ordinary. This is not normal."

Flavio Ribadeneyra, of Huntington Station, came home to find police blocking off part of Nassau Road. He said he also noticed a foul smell Tuesday morning.

"This is unbelievable,” he said. "You would never think that something like that would happen in your building or around your building!"

“It’s pretty heinous,” said Lenny Leavitt, of Huntington.

A medical examiner arrived on scene and took the body away as night fell. Many tell News 12 they're worried as the investigation continues and questions about what happened remain unanswered.

"I have dogs to walk at night. Like, I'm nervous,” said Taylor.

There's no word yet on how long the body was here before it was found, how the person died, nor who the victim is.
