A 33-year-old man from upstate New York was arrested for stalking because his mother was smart enough to trust her gut and use TikTok.

Last month, MaryBeth Nappa went to the Walmart in Cicero, which is near Syracuse, with her daughter to buy school supplies.

The trip to the store seemed normal until Nappa noticed that they seemed to be being followed by a man she had seen leaving the store earlier.

In the now-viral TikTok video, Nappa zooms in on a dark-haired man in a tank top who doesn’t seem to try to hide the fact that his phone camera is pointed at her.

The man looks left and right before returning his eyes to the screen of his phone.

Nappa took out her own phone and started filming the man without him knowing. She later posted the video to TikTok.

In the clip, she says, “So this guy is kind of following me around Walmart while I’m with my daughter.” “He keeps coming after me.

I don’t know him, but he is following me and taking videos of me.”

In the video, Nappa says that she showed the “weird” and “creepy” footage to a store worker, who then told the store manager.

“If you get a bad feeling about something, it’s probably not right,” Nappa told WSYR-TV about her own experience.

Nappa told the station that she went “on high alert” when she saw the man, later identified by police as Eric Fuller, “walk past the aisle we were in, turn around, and stand at the end of the aisle.”

We looked at online records, which show that Fuller was charged with fourth-degree stalking. He has since turned himself in.

Nappa said that since he put the video online, other people have come forward to talk about being followed by other men in the same way.

On Friday, it was not clear if Fuller had entered a plea or hired or been given an attorney. He could not be reached for comment.
