They state that he had set up one camera on the back of a vehicle and another on a ladder to capture the stunt.  In an interview with The Star Tribune of Minneapolis, Lisa Primeau, an aunt of Mr. Ruiz’s, said, “We called him our little daredevil.” Her nephew put “a dangerous twist on everything he did,” she added, once even “jumping into the swimming pool from the top of the house.” 
 
 Ms. Perez told investigators that she had shot Mr. Ruiz from about a foot away while he held a 1.5-inch thick book to his chest, the authorities said. Claudia Ruiz, another aunt of Mr. Ruiz, told WDAY-TV in Fargo that before the fatal shooting, her nephew rationalized the stunt as a way to get more viewers and “get famous.” 
 
 Ms. Perez appears to have posted 18 videos on her YouTube channel since May 9.
– A Minnesota woman charged with fatally shooting her boyfriend in a failed YouTube video stunt foreshadowed the event when she tweeted that it would be "one of the most dangerous videos ever." Monalisa Perez, of Halstad, was charged Wednesday with second-degree manslaughter in the death of Pedro Ruiz III. Perez, who is pregnant and faces up to 10 years in prison, was released on $7,000 bail. According to the criminal complaint, the 19-year-old Perez told investigators that Ruiz wanted to make a video of her shooting a bullet into a book he was holding against his chest. Hours before the Tuesday night shooting, Perez tweeted: "Me and Pedro are probably going to shoot one of the most dangerous videos ever. HIS idea not MINE." The complaint says Ruiz set up one camera on the back of a vehicle and another camera on a ladder nearby. Perez says she fired from about a foot away with what authorities say was a .50-caliber Desert Eagle pistol, which the AP reports is described by retailer Cabela's in an online ad as "one of the world's most powerful semiautomatic handguns." Perez died from a single gunshot wound to the chest. Many of the videos on Perez's YouTube channel are of her and Ruiz playing pranks and performing stunts, with the New York Times noting that most were pretty mild; it cites one video were Ruiz eats a doughnut Perez covered not in powdered sugar, but baby powder. The most recent video was posted the morning before the shooting. "Imagine when we have 300,000 subscribers," Perez says during the video.
