Three men are being investigated over a 15-year-old girl who vanished five weeks ago in Utah — with at least one sharing disturbing sex chats while trying to get her to meet him, according to authorities.

Alisa Petrov, 15, from South Jordan, was reported missing on April 21, two days after her final message to a 41-year-old man with whom she had been having a series of sexual conversations, according to an affidavit obtained by KSL TV.

“I’M RUNNING AWAY. Please don’t contact me,” Petrov wrote on April 19 at 12:34 a.m. in a message to the unnamed man from Herriman, Utah, whom she met on Discord, the report said.

Their chats had become increasingly sexual, including discussions about condoms and sex games, as well as planning to meet in person, according to the affidavit.

The man has not yet been charged, but the unsealed search warrant outlines probable cause for a search of his home and phone, citing evidence of possible enticement and exploitation of a minor, KSL reports.

Messages were discovered on Petrov’s iPad, which she left behind in her bedroom.

She had shared her Snapchat username with him, and some messages may have been deleted, according to the warrant.

Two other men have been charged already over Petrov’s disappearance.

William Taylor Glines, 37, is in custody in Texas, while a second suspect, Matthew Nicholas Menard, 35, of Florida, still hadn’t been located as of Wednesday.
