Texas police are trying to piece together how a woman ended up stuffed inside a cardboard box at a landfill — alive and nearly naked — after a night of partying, NBC reported.

Community service workers stumbled upon the woman, still inside the box, at the Irving, Texas, dump at about 9 a.m. Saturday and called the cops.

The woman, found in only a T-shirt, told investigators the last thing she remembered was hitting a Dallas club with a friend the night before, according to NBC.

A police report obtained by the network says the woman’s friend went to get their car while she waited with a man they’d just met at the bar.

The woman, in her 30s, had vanished by the time the friend returned.

A missing persons report was filed with the cops at 7 a.m., only for the woman to surface about two hours later.

CBS reported that the woman had no apparent injuries, and that a rape exam proved inconclusive.
