The indictment also says nine Egyptian men were part of a smuggling gang that charged each passenger between $4,000 and $8,000 (£3,100 and £6,300) for boat rides.
Prosecutors' charges are based on Coast Guard interviews with nine other survivors in the days following the disaster.
Evidence from the remaining 95 survivors does not appear to have been presented to the court.
Our team has previously heard claims that some of the 104 survivors were pressured to identify nine Egyptian men as traffickers.
Two Syrian men, whom we called Ahmad and Musab to protect their identities, said the Coast Guard instructed them to keep quiet about other factors in the disaster and instead blame these nine men.
“They were imprisoned and unfairly accused by the Greek authorities in an attempt to cover up their crimes,” Musab said.
In separate interviews in Athens, four other survivors said they believed Egyptians were paying passengers like them and had framed them.
However, other survivors have reportedly stated that some of the defendants were actually abused. They were called the Pylos Nine, after the Greek city of Pylos near the site of the sinking.
