: Stunning model killed on visit to Guatemala prison during riot in which 4 people were beheaded

Joanna Birriel has been identified as the stunning 24 year old model who was killed in a Guatemala prison, Mexico while she visited Bryon Lima - one of the country's most powerful inmates. Joanna was caught up in the gang violence which also involved the beheading of four inmates.

According to prison officials, Joanna visited Lima, who was a former army officer, once a month. Prosecutors claim he built a multimillion pound illegal prison empire based on threats and corruption.

The riot began when a fellow inmate threw a hand grenade at Lima and supporters protecting him attacked their rivals with guns resulting in the death of the model.

Officials blamed the violence on a rival gang led by drugs trafficker, Marvin Montiel Marin.



Lima was imprisoned for the murder of a bishop, Juan Jose Gerardi, who was bludgeoned to death with a concrete block in 1998 because the bishop opposed the previous military regime in Guatemala.
