A judge signed an order Friday that denied a motion for a new trial for the 23-year-old man convicted in the January 2020 shooting death of a Donna teen, court records show.

Carlos Julian Contreras was sentenced to 60 years in prison in September after he was found guilty in the shooting death of 18-year-old Genaro Isaiah "Izzy" Castillo. Castillo’s body was found near Donna Lake in January 2020 after he was shot multiple times.

On Monday, a hearing was held after Contreras’ defense team filed a motion for a new trial, arguing that the case was mishandled twice.

As previously reported, a mistrial was initially declared on Sept. 12 after the defense team learned that prosecutors offered immunity to Contreras’ common-law-wife — Miranda Luna — without disclosing it.

During the trial, Luna testified that she witnessed Contreras shoot Castillo after he was forced to do so by a man identified as Jorge Veliz, who was never charged in connection with the shooting.

The filing for a new trial called Luna’s testimony “false” and “misleading.”

Testimony from Monday’s hearing centered on how prosecutors handled the immunity deal made with Luna.

Later that same day, an order denying the motion for a new trial was filed, but it wasn’t signed until Friday.

“The court finds that the said motion is not meritorious, and further finds that defendant has not established entitlement to new trial,” the order stated. “Neither is defendant entitled to an acquittal on double jeopardy grounds. It is therefore ordered and decreed that the motion for new trial be and hereby is denied.”

Contreras was 18-years-old when the murder happened.
