Woman charged in November homicide in east Las Vegas

A woman is behind bars as a suspect in a November homicide.

Las Vegas police identified Betty Ann Marshay Pires, 25, as a suspect in the shooting death of Kevin Thomas in the east Las Vegas Valley on Nov. 22. Pires was booked Wednesday into Clark County Detention Center on a charge of murder with a deadly weapon.

Thomas, 50, was found dead on the road after he was shot about 7 p.m. at 5101 E. Twain Ave., near Nellis Boulevard, police said.

An arrest warrant issued for Pires in April shows she had been living with Thomas. The couple’s relationship was tumultuous, with two documented instances of alleged domestic violence, it said.

Pires initially denied being with Thomas the night he was shot, but detectives discovered the couple had eaten at a Pizza Hut just 30 minutes before the shooting. The arrest warrant indicates Thomas had stolen a gun for self-defense, and the gun was used against him the night he died.
