Two bodies authorities believe to belong to Miss Honduras 2014 and her sister have been found buried near the spa where they disappeared six days ago, the Honduras National Police director said Wednesday.

Authorities are awaiting confirmation from forensic officials that the bodies are Maria Jose Alvarado, 19, and her sister, Sofia, 23, said Gen. Ramon Sabillon.

Both women were shot to death.

Plutarco Ruiz, the boyfriend of Sofia, and an accomplice, Aris Maldonado, have been arrested, Sabillon said.

The sisters were last seen Thursday in a spa in Santa Barbara, about 240 miles (400 kilometers) west of Tegucigalpa, where they had gone to celebrate Ruiz's birthday.

Alvarado, 19, was crowned Miss Honduras in April and was expected to compete in the Miss World Pageant in London next month. She was supposed to have left for London on Sunday.

Sabillon said Ruiz led authorities to the bodies.
