You can't dust for vomit

Okay, this is a little weird. I'm not exactly sure why the cops are involved. Maybe it's part of a crackdown on littering.

Sheriff's deputies in Henry County [Iowa] are stuck in the middle of a less than appetizing investigation. Investigators are trying to find the person who has dumped bags of what appears to be human vomit in ditches in a 1 1/2-mile area northeast of the city.

Deputy Dan Wesley said as many as 50 garbage and trash bags containing regurgitated food has been dumped over the past three years.

Bags, ranging in size from small white trash bags to large black lawn bags, have been found with only a couple of inches of the substance in them, Wesley said.

They ought to keep an eye out for a skinny teenage girl with subscriptions to several fashion magazines. That, or Karen Carpenter.

A sample was taken from one of the bags and sent to a private lab for analysis.

"We haven't found any DNA or anything yet," he said.

[...]

"We were just hoping ... whoever is doing it will stop," Wesley said.

But if that happens, how will you catch this nefarious fiend? I mean, someone definitely ought to be in prison for this kind of crime spree.
