Efrain Guevara

Efrain Guevara was a caring, loving, and genuine young man working to accomplish his goals and make his family proud. Remembered by his mother as funny, compassionate, and hard-working, the 20-year-old Hispanic male was the oldest of three siblings. His life was cut short in a burst of violence at a house party in Las Vegas, Nevada, during the summer of 2024.

On the night of Saturday, July 13, 2024, Efrain was among the guests at a party in the city's eastern valley, near the intersection of Owens Avenue and Mohave Road. The host often used social media to invite people to her gatherings. That evening, a group of males was denied entry because the host did not recognize them. A short time later, around 11:45 p.m., a white sedan drove past the residence. An occupant in the passenger seat opened fire on the crowd of partygoers gathered outside.

The gunfire struck multiple people. Efrain Guevara was hit in the torso and rushed to Sunrise Hospital and Medical Center. He underwent surgery for nearly three hours but ultimately succumbed to his injuries. Another young man, 18-year-old Erick Roque, was shot in the head and pronounced dead at the scene. Several other guests sustained injuries but survived the attack.

Investigators with the Las Vegas Metropolitan Police Department began piecing together the events of that night. Using surveillance footage from the neighborhood and other evidence, they identified two suspects. On August 8, 2024, police arrested Jesus Martin-Guerrero and Noah Sierra, both 16 years old at the time of the shooting. A grand jury later indicted the teenagers, who were to be tried as adults. They faced over 35 charges, including two counts of murder with a deadly weapon, attempted murder, and conspiracy to commit murder.

The mothers of Efrain Guevara and Erick Roque attended every court hearing, determined to see justice for their sons. In October 2025, Martin-Guerrero and Sierra appeared in court to face the charges against them. In February 2026, both defendants pleaded guilty to murder and attempted murder. They were each sentenced to serve 30 years to life in prison.
