COVINGTON, LA (WVUE) - Emotional testimony is underway in a Covington double-murder trial.
Jacob Middleton, Jr. is on trial for the 2014 murders of his father and half-sister.
In opening statements Thursday morning, prosecutors said they had a confession and gunshot residue which they believe should lead to a conviction.
Prosecutors say Jacob, Jr. killed his father and his half-sister Makayla as they slept on an air mattress in their Abita Springs home after watching a Saints game in early January 2014.
Prosecutors also say they both had been shot in the head.
Jacob, Jr. tried to use his father's debit card at a Kenner ATM the day after the murders.
He later confessed, prosecutors say.
But in their opening statements, defense attorneys said the confession was made under duress.
They said Jacob, Jr. had been doing drugs the morning after the murders and they say that the confession came after a 17-hour police interrogation.
The state's first witness, Kelly Bravo, the mother of Makayla described discovering the murder scene after not hearing from Makayla's father for more than a day.
At first, she thought they were sleeping but she broke out in tears as she described discovering they were both fatally shot in the head.
