Timothy Jones Jr. confessed to murdering Merah, eight, Elias, seven, Nathan, six, Gabriel, two, and Abigail, one, at their home in south Carolina, US.
The court heard, he had beaten one of the kids and strangled the other four to death before wrapping their bodies in plastic bags and driving them around for a week.
He was sentenced to death, and the execution is scheduled for November, however there are likely to be years of appeals before this is carried out.
Timothy, who met his former partner Amber Keyzer when he was 22, had previously been to prison for drug offences.
“The worst of the worst know killing your babies is obscene, outrageous and absolutely morally unacceptable”
And whilst in prison he discovered religion and became devoutly local to a church – pledging to honour the bible with everything he did.
After finishing his sentencing, Timothy and Amber got together and quickly married in which Amber discovered Timothy had tradition ideas of how a woman should act.
She found that she was expected to dress conservatively and raise lots of children.
Whilst planning the wedding, Timothy graduated from college and secured a job as a computer engineer earning more than $80,000 a year.
The pair settled in a mobile home in Lexington, south Caroline and had five children.
Timothy, who was known to adore his children, believed he should raise his kids with a firm hand.
Even when social services stepped in – he refused to stop smacking his children in order to discipline them.
However, Timothy was left shaken in 2014 when Amber had an affair with a 19-year-old neighbour.
He began drinking and smoking synthetic marijuana – and quickly slipped into his old ways before he went to prison.
However, he was granted primary custody as Amber didn’t have a job or driving license – while Timothy worked with a hefty salary.
Which meant it was decided it was in the children’s best interest to live with him.
Devastated Amber, who began to study and work, would meet her children every Saturday.
However, police stopped Timothy on 6 September 2014 in his car in Mississippi due to a stench described as the “smell of death” coming from the vehicle.
When police searched the car they found synthetic marijuana along with blood and maggots – at the same time his children had been reported missing.
Timothy confessed to killing his children, by telling police that they were dead and he had dumped them in rubbish bags on hillside in Alabama.
Jones eventually buried their bodies on a rural hillside near Camden, Alabama, days later in 2014, cops said.
At his trial, prosecutors showed the jury a series of lists allegedly written by Jones which appeared to be checklists directing how to mutilate bodies, WLTX reported.
One of the handwritten lists reportedly said: “Head to campground. Melt bodies!
“Saw & bones to dust or small pieces…sanitation plant.”
His lawyers said that Timothy was suffering from mental health issues and could be schizophrenic.
They said that his drug and alcohol abuse, and the fallout of his broken marriage, had made him lose grip of reality.
“He’s crazy,” his lawyer told the jury.
“You can’t rationalise crazy. But at the time, he thought it was the right thing to do.”
However, the prosecution said: “The worst of the worst know killing your babies is obscene, outrageous and absolutely morally unacceptable.
“Jones did that in a matter of seconds.”
Emotions ran high when Amber testified about the breakdown of their marriage and the grief of losing her five children.
At one point she collapsed on the witness stand, hysterical, as she read a letter she’d written to her daughter.
‘My babies! My babies! Oh, God! I’m so sorry!’ she cried, inconsolable.
‘Why? Why? Why?’
The prosecution reminded the jury just how sickening the crimes were in their closing statement.
‘He left his kids out there in bags,’ they said.
‘They looked like garbage.’
In June this year, Timothy was found guilty of killing his five children.
