Argentine authorities recently arrested a nun from Japan who allegedly assisted and even engaged in the diabolical sexual abuse of disabled children in Argentina’s northwestern Mendoza province.

According to Daily Mail, 42-year-old Kosaka Kumiko has been charged with helping Roman Catholic priests molest and rape multiple deaf chilren at a school for youths with disabilities. In a recent court proceding, she has denied any wrongdoing.

Court documents revealed that the fondling, forced oral sex, and rapes were allegedly committed in the bathrooms, dormitories, garden and a basement at the Antonio Provolo Institute for children with hearing impairment in the city of Lujan de Cuyo in Argentina.

Kumiko’s involvement in the systematic abuse came to light after a former student accused the nun of giving her a diaper to cover up a hemorrhage allegedly caused by a sexual assault from priest Horacio Corbacho.

Aside from helping the priests, the nun, who has citizenship in Argentina, has also been charged with physically abusing the students herself. Now under custody at a women’s prison in the city, Kumiko told court officials that she was innocent of the crimes during the court hearing conducted last Thursday.

Local authorities also arrested Corbacho, fellow priest Nicola Corradi, and school employees Jorge Bordon, Jose Luis Ojeda and Armando Gomez last November after 24 students from the Provolo Institute reported the alleged crimes. According to the children, the two priests repeatedly raped and molested them.

During an inspection of the school, the police discovered piles of pornographic magazines and about $34,000 in Corradi’s room.

“They always said it was a game: ‘Let’s go play, let’s go play’ and they would take us to the girls’ bathroom,” one of the accusers claimed.

Currently, investigating officials are reviewing over 30 testimonies against the priests and teaching staff. The accused face a maximum sentence of 50 years in prison if found guilty.

Corradi had previously been embroiled in a similar scandal a few years ago when he was accused of abusing students at the Provolo Institute in Verona, Italy. It is believed that hundreds of children have been sexually assaulted by two dozen priests and religious brethren in the Italian school for the disabled.

Critics have expressed outraged that Corradi was never punished by the Vatican and instead allowed to allegedly continue his abuses in Argentina.
