Who Is Monalisa Perez? YouTuber Tweeted About 'Most Dangerous Video Ever' Before Killing Boyfriend

The Minnesota teen who shot and killed her boyfriend in a YouTube stunt gone wrong Tuesday posted an ominous and foreshadowing message on Twitter just hours before the shooting. Monalisa Perez and her boyfriend, Pedro Ruiz III, reportedly wanted to achieve YouTube fame and get more subscribers on their channel.

To achieve that fame, the pair decided they would film a stunt in which Ruiz held up an encyclopedia to his chest while Perez fired a gun at the book. The encyclopedia was meant to stop the bullet.

“Me and Pedro are probably going to shoot one of the most dangerous videos ever,” Perez tweeted Tuesday. “HIS idea not MINE.”

The pregnant 19-year-old described herself on her Twitter as a “mother of two” who “loves to laugh, positive energy” and a “stay at home mommy” and “family vlogger.” She had started her fledgling YouTube channel, La Monalisa, just a few months before. So far, the account had about 10,000 subscribers.

The pair had other YouTube videos on the page involving stunts and pranks, though the others were far tamer. The most recent video, posted the day before the shooting, was entitled “Doing Scary Stunts At The Fair, Part I.”

The gun stunt, however, didn’t go as planned. The couple set up two cameras to capture it: one on a ladder and the other on the back of a car. But when Perez fired the gun from about a foot away, the bullet went through the book and pierced Ruiz in the chest. The gun she used was a .50-caliber Desert Eagle pistol, described as “one of the world’s most powerful semiautomatic handguns.”

Ruiz, 22, died from a single gunshot wound.

His aunt, Claudia Ruiz, said the idea, was, in fact, her nephew’s. She said he liked to put “a dangerous twist on everything he did,” and once jumped from a roof into a swimming pool below.

“He told me about an idea,” she told Valley News Live Tuesday. “I said, ‘Don’t do it, don’t do it. Why are you going to use a gun? Why?’ ‘Because we want more viewers.’”

She said the couple had tested the idea earlier and the bullet hadn’t gone through the book, a fact confirmed by Norman County Sheriff Jeremy Thornton. The video from the shooting would not be released, according to NBC News.

Ruiz and Perez already had a 3-year-old daughter together, who was featured in some of their videos, and Perez was pregnant with a son.

“They were in love,” Claudia said. “They loved each other. It’s just a prank gone wrong. It shouldn’t have happened like this. It shouldn’t have happened at all.”

Perez was charged with second-degree murder Wednesday but was released on bail. The teenager could face up to 10 years in prison should she be convicted.

“The fact that she has got to live with this for the rest of her life,” said Claudia. “That alone is a charge to me.”
