Four people were found dead early on Thursday morning at two separate residences in the small Nebraska town of Laurel when police responded to reports of explosions and fires at the homes, authorities said.
When local police and fire departments arrived at the first residence, they found the first victim.
A short time later, a second fire was reported at a home several blocks away, where three more victims were found.
“Foul play is suspected in these deaths,” Colonel John Bolduc of the Nebraska State Patrol said at a news briefing.
A silver sedan was spotted leaving Laurel — a small farming community located about 64 kilometres west of Sioux City, Iowa — soon after the second fire, Bolduc said.
“We would describe that individual as a person of interest,” Nebraska State Patrol spokesperson Cody Thomas said in a text message, referring to the driver of the silver sedan.
