Father's confession that he killed his three sons aged 7, 4 and 3, can no longer be used in court because his Miranda rights were violated, judge rules

A father's confession that he killed his three young sons can no longer be used in court because his Miranda Rights were violated, an Ohio judge has decided.

Chad Doerman, 33, admitted to killing his sons - Clayton, seven, Hunter, four, and Chase, three - when he was arrested last summer in Monroe Township, around 20 miles east of Cincinnati, police claim. 

But detectives failed to properly inform him of his right against against self-incrimination and his right to an attorney as they took him into custody, according to a ruling by Clermont County Common Pleas Judge Richard Ferenc.

Moreover, investigators did not stop interrogating Doerman after he explicitly invoked his right to counsel, the judge decided.

As a result, none of the statements the alleged killer made in the interview will be allowed during his trial, scheduled for July.

Detective Michael Ross said the father said during the interview that 'The Bible says you kill your first born, you kill your second born, you kill your third born'

Doerman updated his Facebook page to include this picture just six days before the murders

'The Defendant's Miranda rights were violated when the custodial interrogation continued after the defendant had unequivocally and unambiguously invoked his right to counsel when he told [the detective], "I'll wait for a lawyer, I don’t know, give me a couple of days, I can talk to a lawyer and get nice good answers,"' Ferenc wrote 

Detective Michael Ross said the father said during the interview that, 'The Bible says you kill your first born, you kill your second born, you kill your third born. 

Doermen then reportedly added: 'But first you’re supposed to kill your wife. I didn’t kill my wife.' 

Prosecutors have previously claimed Doerman planned the executions for months. 

Doerman, allegedly lined the boys up before fatally shooting them with a rifle, also injuring their mother when she tried to protect them. 

Chief prosecutor David Gast said during Doerman's arraignment that one of the boys tried to flee into a nearby field but Doerman 'hunted' him down and brought him back to their home before killing him. 

Deputies responded to the home in Monroe Township shortly before 4:30pm Thursday after receiving two 911 calls, one apparently from the mother who was screaming that 'her babies had been shot.' 

Another call came from a passing motorist who said a girl was running down the street saying her father was killing people, a news release from the Clermont County Sheriff's Office said.

The deputies found three boys outside the home with gunshot wounds and tried to save their lives, but the children died at the scene.

Haunting police bodycam footage shows the moment officers arrived to find Doerman calmly seated next to his rifle moments after allegedly executing his young sons.

Doerman was detained without incident after he was found on the steps of his Ohio property.

'I ain't gonna hurt nobody,' Doerman told arresting officers as he told them that his dog wouldn't bite them.

'Shut up, dude. You have the right to remain silent. F***ing use it,' a deputy tells him.

The sheriff's office said the 34-year-old mother, who was not identified, was outside the home and had suffered a gunshot to the hand while trying to shield her sons from their father. 

Doerman's father, Keith Doerman, has said he and his wife are 'still trying to comprehend' how their son could have allegedly killed his own boys, but added they have 'no answers.'

'He just snapped,' Keith said. 'There was something going on in his life that he couldn't handle no more. I can't talk to him, they aren't letting me talk to him so I don't have any answers. He probably hid a lot of stuff from me.'
