These stories are the result of a joint investigation by Toronto Star reporters Robert Cribb, Jennifer Quinn and Julian Sher, and El Nuevo Herald reporter Juan O. Tamayo.
For the two Cuban girls, 12 and 13 years old, it was just another sex party with foreign tourists videotaped, fueled with marijuana and alcohol and sometimes involving sex with both men and women.
But this time 12-year-old Lilian Ramírez Espinosa, an asthmatic, gasped and blacked out.
Her badly decomposed body was found five days later on the isolated outskirts of the eastern city of Bayamo.
The girls had been prostituting themselves for six months, but one of them had to die before the authorities noticed, said Havana lawyer Laritza Diversent, who is helping with the appeal by one of the defendants in the case.
Lilian death on May 14, 2010, is the best documented and most horrifying example of child prostitution to emerge from Cuba since sex tourism began to blossom there in the early 1990s.
Canadian, Spanish and other tourists are flying to the island for sex with minors, a joint investigation by The Toronto Star and El Nuevo Herald has shown, although the extent of the problem remains unknown.
Cubas government resists discussion of issues that might suggest weaknesses in the governing and social system, said one report on child sex trafficking, written by U.S. diplomats in Havana in 2010.
Diversent said she was not surprised that girls as young as the ones in Bayamo were having sex-for-pay in a country where kids generally start having sex at the age of 12 or 13 and families face shortages of everything from tomatoes to shoes.
The only thing never rationed was sex, she said.
What was surprising, Diversent added, was that three Italians and 10 Cubans were tried and convicted in Ramírez death.
Simone Pini, 45, and Angelo Malavasi, 48, are serving 25-year prison sentences for murder and corruption of minors while Luigi Sartorio, 48, was sentenced to 20 years. The Cubans received sentences ranging from 20 to 30 years.
Diversent, who is helping Pinis appeal and has the documents from the trial in September of 2011, said that while aspects of the case remain unclear she does not doubt the two girls were having sex for pay.
Lilian previously had love relations with four Cuban males aged 14 to 25, the lawyer added, reading from a police report. And the sex parties had been going on since mid-2009.
Nancy Muñoz Yero, the mother of one of the Cuban adults convicted in the case, said Ramírez and a girlfriend were known to hang around with foreigners visiting Bayamo, as well as local adults.
Pini said he did not know any of the girls and nothing about any sex parties, but added that Bayamo residents had told him the girls did their little things. They didnt play with dolls.
The courts final ruling in the case never mentions the word prostitution, Diversent said, although it notes that some of the girls in the sex parties received cash or gifts, such as clothes.
One of three prosecution videos presented at the trial shows one 13-year-old recounting sex encounters with both foreigners and Cubans, both men and women, with what was called horrifying casualness.
The videos also show some of the defendants recreating the events in the home and bedroom where they took place, as well as the recovery of Lilians body. They were posted on the Internet by the dissident news agency Hablemos Press.
