Her kills began subtly. A delivery man, lost on a backroad; a couple too drunk to notice she’d driven them off the highway. Jennifer claimed their lives, preserved their meat in her walk-in freezer, and sold it to neighbors, all the while documenting her “harvest” on VK in cryptic posts: “Nature’s cycle demands sacrifice.”

Jennifer escapes, wounded, into the wilderness. Her VK account is shut down, but the platform’s dark corners retain her legacy. Marcus recovers, only to find a package at his door: a frozen package labeled with his name and a post-it reading “For your sister. – Белая Мать.”

I should outline the key points: Jennifer's background as a butcher with a hidden dark side, the use of VK to interact with victims or the public, the investigation unfolding, and the climax where her crimes are exposed. Themes of identity, duality, and the dark side of the internet could be explored. Need to ensure the story flows well, with a balance between the horror elements and the tech aspect from VK. Also, make sure to resolve the story with either her downfall or an unexpected twist.

The police, led by grizzled detective Marcus Cole, dismissed the disappearances as accidents. But when a body surfaces in the river—skin flayed with surgical precision—Marcus notices strange details: a social media clue, a cryptic VK message signed “Белая Мать,” and a barcode carved into the victim’s flesh, matching a post in Jennifer’s VK group.
