A person of interest whom the police believe last entered into the apartment of a missing 19-year-old Florida woman has been found dead, according to authorities.  

Miya Marcano was last seen around 5 p.m. on Sept. 24, at the Arden Villas Luxury Apartments in Orlando, where she lived and worked. 

Police suspected Armando Manuel Caballero, 27, who had been working in maintenance at the complex as a person of interest after Marcano was reported missing, reported KNSD

Orange County Sheriff John Mina said Caballero had shown romantic interest toward the victim, which Marcano had rebuffed. 

Caballero told detectives that he had seen Marcano last around 3 p.m. while at work. But, police found that Caballero had entered Marcano’s apartment using a maintenance key, perhaps before her shift ended.

"We now know that a maintenance-issued master key fob, which Caballero was known to be in possession of, was used to enter Miya's apartment Friday afternoon, at about 4:30. This would have been about 30 minutes before she should finish her shift at the apartment complex," said the Sheriff during a news conference.

Investigators issued an arrest warrant for burglary against Caballero after it was found that he snuck into the victim’s apartment. Police were searching for Caballero throughout the weekend. He was found dead in a Seminole County apartment on Monday. Caballero appeared to have killed himself, said police. 

The missing woman’s family said Marcano was supposed to take a flight to Fort Lauderdale on Friday but she did not contact them after getting off work. She did not board the flight, according to WESH

"Obviously her family raised this level of alarm and concern knowing Miya would never not be in contact with them, would never turn off her phone and never let her phone battery drain completely down," added Mina.

Marcano is still missing. 

Police are reviewing surveillance videos from Marcano’s apartment complex and the building where Caballero was found dead.
