Investigators had been stationed at 40 Second Street since before 10:00 Wednesday morning.
For nearby neighbors, it was a nerve-wracking way to start their day.
"I just came outside and there was cop cars outside and I figured something was going on," Candice Tracy, a neighbor, said. "And then more people showed up and then I figured once they put the tape up, it started getting bad."
Candice Tracy and her seven-year-old son live across the road from 40 Second Street.
At around 9:45 Wednesday morning, Bangor police and firefighters arrived at the apartment building for reports of an injured person. Once inside, officials discovered a dead male.
"We notified our criminal investigation division, and they are currently on scene and probably will be on scene for the next several hours as they begin an investigation into what we believe is a suspicious death at this point," said Bangor Police Sgt. Wade Betters.
Police would not say why they believe the death is suspicious, but say folks have no need to worry.
"At this time we have no reason at all to think the public at large is in any danger," Sgt. Betters said.
But neighbors like Tracy say they're still concerned
"Safety wise, yeah, living across the street and having something like this going on is scary, especially for my kid," Tracy said. "When you don't have any information, I think that kind of hypes the scare factor."
No charges have been filed yet in relation to the incident, as police are still trying to determine if a crime has been committed.
