On Monday morning, patrol officers were in the 3800 block of Alice Street when they saw a pickup truck parked along the street.
Neighbors told ABC13 they saw the truck parked there for days.
"I came back in the house from sweeping the porch off and it was still sitting there," a neighbor said. "I said, 'Oh well, maybe it broke down or something.'"
When the officers approached the vehicle, they detected a strong odor inside.
Once the officers opened the door, they saw a comforter covering a man in the driver's seat, police said. The man in the truck appeared to have suffered multiple stab wounds to the neck.
"My daughter told me that they had found a body over there and the car had been parked over there for a couple of days," Anthony Brown said. "I was like, 'That's too close to comfort man.'"
While details surrounding the death investigation were limited, police described the suspect as a Hispanic man about 5 feet 6 inches tall and weighing about 150 pounds. The suspect was last seen wearing a yellow work shirt and tan work boots.
The death has neighbors on alert.
"It makes you more aware," Brown said. "It makes you more attentive and focused on what's going on around you."
There is no known motive in the incident at this time, according to police.
