An unidentified body was found on a street in Maplewood, New Jersey, Monday morning, authorities said.
Authorities discovered the body of a man on Wyoming Avenue near Hickory Drive at about 4 a.m., police said.
The victim has not been identified, according to the Essex County Prosecutor's office.
It was not immediately clear if the victim was hit by a car or died from other causes, authorities said.
Police officers knocked on neighbors' doors as they investigated.
"They asked us if we knew about a hit-and-run outside the house," said a resident named Nat Francis.
"We heard four guys in a car stopped and they thought it was a deer, then saw the guy who was unconscious," he added.
The prosecutor's office couldn't confirm it was a hit-and-run and said it's waiting on an autopsy.
The body was found feet from Dave Pressel's home but he said he didn't hear anything.
"I have absolutely no idea what happened, how it happened, really when it happened," he said. "All I know is someone unfortunately died from it."
Pressel said the street was a "very typical residential, suburban neighborhood," with many joggers, dogwalkers and bikers around.
