Authorities in Florida are still searching for missing 19-year-old college student Miya Marcano, USA Today reports. Marcano was last seen at work on Friday at 5 p-m, the Orange County Sheriff's Office said. Marcano lived and worked at Arden Villas, an apartment complex about a mile from the University of Central Florida. 30 minutes prior to Marcano leaving work, a maintenance worker at the complex, 27-year-old Armando Caballero, used a master key to access her apartment, Orange County Sheriff John Mina said. Caballero was considered a person of interest in the case, but on Monday, authorities found Caballero dead from an apparent suicide. The Orange County Sheriff's office asks anyone who may have seen Marcano or Caballero, to call law enforcement.
