Donavan Carriaga was found not guilty of killing Adam Messier in 2017.
On Wednesday afternoon in the Superior Court of Guam, a jury found Carriaga not guilty of complicity to commit murder as a first-degree felony and the lesser included offense, complicity to commit manslaughter. Carriaga was also alleged to have used a deadly weapon in the commission of the murder, but since he was acquitted of the murder charge, he was inherently not guilty of using a deadly weapon.
The charge stems from the 2017 death of Adam Messier in an upper Tumon condominium. Carriaga was charged in 2021, along with two others, Curtis Blas and Brandon Flaherty, when Messier's remains were eventually found four years after his death.
After the verdict was read, Carriaga's head dropped. He began to cover his eyes and face, all while emotions began to pour out and his lawyers embraced him. He was then told he would be released of all conditions, primarily having to wear an electronic monitor around his ankle.
Carriaga faced life in prison for the charge if he had been found guilty.
The verdict means all individuals charged in connection to Messier's death have had their cases resolved. Blas pleaded guilty to aggravated assault and is serving 10 years in prison for his involvement. Flaherty also pleaded guilty in exchange for testifying in Carriaga's trial and is pending sentencing. Jason Alianza, Messier's roommate at the time, was also allegedly involved in orchestrating the attack but reportedly died in 2019.
