Tuesday the court heard what Allen told a Texas Ranger last December after he was arrested in Wise County for the murder of his ex-wife Tracey, who vanished from Altus back in 2001.
Last December Allen led authorities to a remote spot between Altus and Lawton where they say he told them he buried his wife.
His arrest came after the reality TV show Cold Justice zeroed in on the cold case.
As he choked back tears, Garland Allen listened with the rest in the Jackson County courtroom in Altus to the emotional statement recorded by Texas Rangers about the death of his ex-wife Tracy.
Allen is accused of murdering of his ex-wife Tracy in 2001.
Authorities say in December, he led them to the remains of his ex-wife near Tom Steed Reservoir.
Police say in May, 2001 Allen told his mother that his wife ran away with another man.
Authorities say the couple had a history of domestic disturbances and custody issues over their two children, and the couple had divorced the year before Tracy vanished.
An Altus detective began working with Cold Justice investigators last year, and a warrant was issued for Allen.
He was then arrested in Wise County.
After several days of excavation, his ex-wife's remains were found in a remote area of Kiowa County.
In the recording played on Tuesday, Allen is heard telling a Texas ranger that he and his wife got in an argument about custody of the children.
Allen tells the ranger he threw her out of the trailer house in Altus and she fell down the stairs and she hit her head, Allen tells the ranger he had no intention to kill her.
The recording continued with Allen tearfully telling authorities he picked her up and put her in his lap and that's when she died, that's when he said he wrapped her in a blanket and buried her at Tom Steed Reservoir in Kiowa County.
Allen is facing trial for two charges, one for murder and the other for removal of a body.
The defense is asking for manslaughter in the first degree because they say it was a crime of passion and Allen did not intend for his wife to die.
But prosecutors are asking for murder in the second degree.
Allen's arraignment has been set for September 2nd.
