After a welfare check at Uyar's home found no one inside, the New Jersey State Police issued an Amber Alert that was sent to privately owned cell phones, broadcast on electronic billboards along highways in New Jersey and beyond, and widely shared via social media.

Rios remains in Tennessee pending extradition back to New Jersey.  An autopsy performed on Uyar revealed her manner of death to be a homicide.
