Carjacker holds couple hostage before killing husband in front of pregnant wife

A gunman held an expectant couple hostage during a deadly rampage in which he killed two people before shooting himself dead.

Dangelo Dorsey also injured three people during a violent series of shootings and carjackings in Tennessee that ended with a high-speed chase as he fled police on Sunday.

He shot himself in front of the pregnant wife of a man he had killed earlier after holding them hostage when he carjacked them as they went to church.

David Rausch, director of The Tennessee Bureau of Investigation, said in a press release that the killing spree started at 9.30am when the 29-year-old opened fire inside a moving vehicle along Interstate 24 near Beechgrove.

Dorsey, from St. Louis, Missouri, got out of the vehicle as traffic came to a halt shooting a woman in her hand as he attempted to carjack her vehicle and he fatally shot a nearby truck driver in the face.

Aileen Stevens was teaching Sunday School that morning at her church in Rutherford County and was on her way there with husband Jordan in their Ford Mustang when they were rear-ended by Dorsey.

Mr Rausch said the couple were forced to drive back to their home at gunpoint by Dorsey who is claimed to have stolen two of their guns before he made them swap cars and go back out with him.

Police say at some point Mr Stevens was shot dead in front of his wife by Dorsey who dumped the body before driving off with the terrified mum-to-be.

Officers managed to pinpoint the SUV they were in and a 100mph police chase began before the car crashed and flipped.

Mr Rausch said Dorsey then shot himself dead in front of Mrs Stevens.

He added: “The female hostage was safely recovered.”

Mr Stevens’ body was later recovered along Interstate 24 westbound.

Police have officially named Dorsey’s two victims as 23-year-old Mr Stevens and Darcey Johnson, 28.

Mrs Stevens, who is a kindergarten teacher, is four months pregnant with their first child, her brother Eliezer Rostran said, CNN reports.

Her husband worked in construction and the high school sweethearts would go to church together before spending time with family afterward.

Mr Rostran said their mum goes to the same church as the couple and she became concerned when they failed to show up.

He said: “That’s how she knew something was wrong.”

Mr Steven’s mum Michelle told WTVC her son begged Dorsey to spare his wife and their unborn daughter and take him instead.

The expectant mum and unborn child are doing well, she said.

She added: “I want everyone to know Jordan died a hero.”

Mr Rausch said that Dorsey had no adult arrest record in Tennessee but had a lengthy criminal history in Missouri.

There were no outstanding warrants for his arrest at the time of the killings.

“I want to extend our deepest sympathies to the innocent lives that have been impacted by the set of events,” he added.
