A law enforcement source told CBS 4 News investigators believe recklessness contributed to the crash, thus the severity of the charge.

Police said Ferreiro was speeding and ignored posted signs when he plowed the bus into an overpass at MIA’s arrivals area on December 1st 2012.

More than 30 people were on-board the bus at the time of the crash.

Most of them were rushed to hospitals. Three did not survive.

Serafin Castillo, 86, Francisco Urana, 56, and Gliceria Garcia, 75, all died from their injuries.

They were part of a Jehovah’s Witness group en route to Palm Beach for a religious conference.

Authorities said Ferreiro was lost and made an unintentional detour into the airport.

A source said Ferreiro could face additional charges related to all the other people who were hurt in the crash.

His bond is currently set at $50,000.
