Authorities started the search after the boy wasn’t dropped off at day care and Uyar didn’t arrive for her scheduled work shifts. The boy eventually was found unharmed at a hotel in Monterey, Tennessee, when Rios was taken into custody.

Uyar's body was found a day later almost 700 miles away in a wooded area off of I-40 in Tennessee. An autopsy revealed that she died as a result of being strangled and blunt force trauma.

A motive for the slaying has not been disclosed. Authorities have said the couple met in high school and dated on and off for years.
