Two Separate Murder Arrests Land Suspects at Clark County Detention Center

A southeast valley shooting death and a domestic homicide each resulted in arrests and bookings at Clark County Detention Center on Tuesday.

Las Vegas Metropolitan Police Department made arrests in two unrelated homicide cases on Tuesday, booking an 18-year-old suspect in a southeast valley shooting murder and a man accused of killing his wife at their home near Valley View Boulevard and Sahara Avenue into the Clark County Detention Center. The cases, investigated separately by LVMPD, each involve open murder charges and underscore a busy week for homicide investigators in the Las Vegas valley.

Second Suspect Arrested in Southeast Valley Shooting Death

Las Vegas police arrested 18-year-old Quin'Marion Washington on Tuesday in connection with a shooting that left one man dead in the southeast valley earlier this month. Washington was booked into Clark County Detention Center on several charges, including open murder with a deadly weapon and attempted robbery with use of a deadly weapon.

Officers originally responded to a report of a shooting in the 5700 block of Missouri Avenue, near Tropicana Avenue and Boulder Highway. Upon arrival, police found a man inside a car that had collided with a building, suffering from multiple gunshot wounds. He was pronounced dead at the scene.

During the investigation, police determined that three men had approached the victim while he was sitting in his vehicle. During the altercation, one of the suspects allegedly began shooting the victim, who then fled in his car before crashing into a nearby structure. The suspects fled the area before responding officers arrived.

Washington is the second suspect to be arrested in the case. The first, 19-year-old Elijah Harris, was previously identified and taken into custody. Harris was booked on suspicion of open murder, conspiracy to commit murder, and conspiracy to commit robbery, and is expected in court on May 20th.

Husband Arrested After Wife Found Dead at Las Vegas Home

In a separate case, a Las Vegas man was arrested early Tuesday morning after his wife was found dead at the couple's home near Valley View Boulevard and Sahara Avenue. First responders received a 911 call around 3 a.m. from a man who reported that his wife was injured and needed assistance.

Medical staff who arrived on scene found the woman dead and grew suspicious, prompting them to request a police response. According to investigators, the husband told officers that he and his wife had gotten into an argument earlier that night and that 'something bad had happened.'

The husband was identified as Roelmer Sanchez-Garrido. Police took him into custody and began investigating the death as a homicide. During the course of their investigation, police learned that Sanchez-Garrido's wife had been trying to leave him and take their children with her. Investigators believe the argument turned physical and resulted in her death.

Police confirmed that at least one child was inside the home when the incident occurred. That child was taken into child protective services. As of Tuesday afternoon, the wife's cause of death and identity had not been released, pending notification of next of kin.

Sanchez-Garrido is being held at the Clark County Detention Center on one count of open murder. Jail records indicate he was set to make his initial court appearance on Wednesday morning. Lt. Robert Price shared initial details of the investigation with local media.
