Guillermo Amador III will serve 31 years in prison for the murder of Emilie Gomez and the assault of Dallas Massaro, authorities announced Monday.

On Dec. 5, 2022, Amador, who was 17 years old at the time, orchestrated “a violent drug robbery using a fake Instagram account to lure Dallas Massaro to a remote location under the guise of a marijuana and THC vape sale,” according to a release from the Maricopa County Attorney’s Office.

Massaro brought his girlfriend, Emilie Gomez, to Buckeye “assuming it would be a straightforward transaction,” the release stated.

After a brief conversation, Amador pulled a gun, fatally shooting Gomez in the face and critically shooting Massaro, leaving him with severe, lifelong injuries, according to MCAO.

Amador then stole a bag of marijuana and THC vapes from the victim before fleeing the scene.

Amador pleaded guilty to one count of second-degree murder and one count of aggravated assault.
