TEMPE, AZ — A woman has died after she was violently attacked and stabbed by her boyfriend at their Tempe apartment on Sunday morning, according to Tempe police.

The boyfriend has been arrested in connection to her death.

In a Monday afternoon news release, the Tempe Police Department identified the woman as 23-year-old Tammy Begay.

The alleged suspect was identified as Mason Nez, 23.

"This horrific and violent attack undoubtedly has affected so many lives. Our thoughts and prayers remain with the entire Begay family and friends," the police department said in a statement.

Police said around 3 a.m. Sunday, officers responded to the clubhouse of an apartment complex near Scottsdale and Curry roads, north of the Loop 202, after reports of a stabbing.

There, officers found Nez on the floor apparently holding the woman, who had "obvious signs of trauma" including multiple stab wounds, according to Tempe police and court documents.

Officers attempted life-saving measures before paramedics arrived and transported the woman to the hospital, where she later died, police said.

Nez was arrested and booked into jail on one count of first-degree murder, court documents state. He is being held on a $1.5 million secured bond.

Court documents also state that the entire attack was captured on surveillance video.

No additional details were released and a police spokesperson said they would not conduct media interviews at the time.
