MonaLisa Perez, 20, remains in jail after shooting her boyfriend Pedro Ruiz at short range on Monday, the StarTribune reports. The couple was recording a stunt for their YouTube channel outside their Minnesota home.
According to CBS Minnesota, Ruiz was holding a thick book in front of his chest and instructed Perez to shoot at him with a .50-caliber pistol. They wanted to see if the book could stop the bullet. The pair reportedly had tested the stunt out already—they were filming when the shooting occurred. Police said there are "multiple videos" of the incident, but that none of them will be released at this time.
"They were in love. They loved each other. It was just a prank gone wrong. It shouldn't have happened like this. It shouldn't have happened at all," Ruiz's aunt Claudia told Valley News Live.
She also said the pair was trying to achieve YouTube fame and grow their following with increasingly dangerous stunts. "He had told me about an idea. I said, don't do it, don't do it. Why are you going to use a gun? Why? Because, we want more viewers."
