An Orange County man has been arrested on suspicion of stalking a professional online gamer during a multi-year harassment campaign, the Justice Department said.

Evan Baltierra, 29, of Trabuco Canyon, was arrested Monday by FBI agents and was scheduled to appear in U.S. District Court in Santa Ana.

He is charged with one count of stalking and, if convicted, would face a statutory maximum sentence of five years in federal prison.

According to the arrest affidavit, Baltierra orchestrated a campaign of harassment against the woman who used the name Nali in her role as a high-profile World of Warcraft player on the streaming platform Twitch. At one time, he had been a moderator of her stream channel.

Baltierra met Nali in person in November 2019 during a fan meet-and-greet at the gaming convention Blizzcon in Anaheim. He reportedly expressed romantic interest in her, and she declined, saying she had a boyfriend.

In June 2020, after being told that Baltierra was trying to find her address so he could visit her in Canada, she removed him as moderator of her stream channel and blocked him from her social media.

What followed, she said, was months of threats and harassment against her and her boyfriend, including distribution of images in which her face was put on sexually explicit photos.

Nali went public with her allegations in December 2020, when she sought crowdfunding support for pursuing legal action against Baltierra. Two months later, she quit her gaming career, citing the stress of his “constant harassment.”

That same month, February 2021, she obtained a temporary restraining order against Baltierra in Orange County Superior Court, and he signed an agreement to end the harassment campaign.

But the arrest affidavit said he continued to stalk the victim.

In March 2022, a search of Baltierra’s residence turned up “many photoshopped nude images with the victim’s face on them” and evidence of email accounts from which harassing messages were sent, the affidavit states.

Baltierra joined the Marine Corps upon graduation from Mission Viejo High School, according to a 2011 article in the Orange County Register. In April 2019, he was sworn in as a Los Angeles airport police officer. It is not known how long he held that post; online government records indicate he was paid only in 2019.
