HALSTAD, Minn. - A Minnesota woman charged in the fatal shooting of her boyfriend told authorities it was a video stunt gone wrong.

Monalisa Perez of Halstad was charged Wednesday with second-degree manslaughter in the death of Pedro Ruiz III.

According to a criminal complaint filed in Norman County the 19-year-old Perez told authorities Ruiz had wanted to make a YouTube video of her shooting a bullet into a book he was holding against his chest for quite some time. On Monday she finally agreed, and fired from about a foot away as he held the book to his chest.
