Tammy Begay was a 23-year-old student studying dental hygiene at Carrington College and a member of the Navajo Nation.
Fran Tah, 34, and Ariel Tah, 16, were a mother and daughter, also members of the Navajo Nation.
Early Sunday morning, Begay was stabbed to death by her boyfriend Mason Nez, 23. Nez was captured on the building’s surveillance footage, stabbing and beating Tammy inside the complex’s clubhouse.
On April 13th, Fran and Ariel Tah were murdered by Herbert Jefferson Sr. (their father-in-law and grandfather respectively) at the Cliffside Apartments in Gallup.
Begay and Nez dated sporadically for over a year. Their relationship was described by those who knew it as being tumultuous. Tempe police were previously contacted to intervene in the couple’s relationship during March and July of the last year when there were allegations of Nez assaulting Begay.
A source close to the family claimed that Jefferson had been abusing his granddaughter leading up to the killings.
Nez now faces first-degree murder charges for Begay’s killing.
Following the murders of his daughter-in-law and granddaughter, Jefferson returned to his home in Fort Defiance, Arizona, and took his own life.
