Investigators say Hosea Metcalf gunned down Benny Word, 41, outside the home Metcalf shares with his girlfriend at the corner of North Powell Street and Williams Avenue around 7 a.m. Saturday.
Word was pronounced dead at the hospital.
Detectives say Word, Metcalf and his girlfriend were involved in a love triangle, and Metcalf shot Word after finding him outside their home.
"You know how that goes, when someone’s in love and you catch someone else in your house, ain’t no telling how it might go," said neighbor Yvonne Nichols.
People on the block were jolted awake by the sound of gunfire.
"I heard five gunshots," said neighbor Bruce Kelly.
Kelly says he didn't go outside, but knew whatever happened wasn't good.
"Something bad happened," he said. "When I got up, I seen a lot of police – the police was out here. And the police came to the house asking questions."
Another neighbor tells WREG she called 911 after hearing the shots and seeing a body laying in the middle of the street.
Nichols says she vaguely knew Word and has known Metcalf for a long time.
"I’ve been knowing him very well and I haven’t never known him to bother no one," she said. "He’s a good guy. He’s a real good guy."
She blamed police for the violence, saying officers should spend more time patrolling the neighborhood.
"If the Forrest City Police Department do their job, stuff like this wouldn’t even go on," Nichols said.
Investigators initially said they were questioning two people of interest in the case, but now say Metcalf's girlfriend has been cleared.
No bond has been set for Metcalf yet.
Word was also in the news last fall after he was shot in the chest by a 68-year-old man who was later arrested.
