Another horrible dream

There is an old broken abandoned parking garage. There has been a reward out for a missing girl for some time now. A female FBI agent got a tip about a old parking lot. She goes alone and looks around. She sees an old broken car. Next to it is a space were a car would usually park, but it is dug up like a grave and filled with rocks . She gets down and starts removing the rocks. She gets down 2 inches before she see part of an arm. She hurries now and starts to see a nose, then a cheek, then an eye, finally she uncovers the entire face and screams. She backs up screaming...

"He petrified her!!!" she says.
The killer had preserved the girls terrified face until she had gone into rigor mortis.
