HALSTAD — A Minnesota woman has pleaded guilty to fatally shooting her boyfriend in a videotaped stunt they planned to post on YouTube.

According to a press release, 20-year-old Monalisa Perez pleaded guilty last week to second-degree manslaughter in the June death of 22-year-old Pedro Ruiz III.

Court records said Perez told investigators that Ruiz wanted to make a video of her shooting a bullet into a book he was holding against his chest. Perez said she fired from about a foot away. Ruiz died from a single gunshot wound to the chest.

The couple had a YouTube channel where they posted videos of pranks and stunts.

Perez’s plea agreement calls for her to serve six months in jail and 10 years’ supervised probation. She’ll be sentenced in February.
