Here's the thing

So there's this guy, right? And he's a serial killer - but he doesn't like to get his hands dirty. He drives around in a pickup truck - the front cab is packed full of stuff, so there's no room for anyone else.

Serial Killer is on the on-ramp of the freeway and stops to pick up a hitchhiker, one of those guys you see by the side of the road wearing a dirty wife beater, a week of beard growth, with a limp cigarette hanging out of his mouth. He may or may not have a mangy dog with him. Let's say not, because I like dogs.

The serial killer stops to pick up the hitchhiker, but there's too much stuff in the cab. SK leans out the window of the picket and tells HH that he can ride in the trailer. It's one of those classic teardrop trailers, made of aluminum. SK tells HH that he's just finished refurbishing the trailer and is on his way to deliver it to the family that just bought it.

HH thinks it's a bit odd that SK would allow him to ride in the trailer, especially since HH is a bit rank, smelling of booze and urine, but a free ride is a welcome thing.

The trailer has nothing but smooth polished metal inside, but still cool since it's morning. It's clean and antiseptic, smelling vaguely of chemicals. HH finds a woman's bracelet on the floor of the trailer and pockets it.

They've only gone a mile down the freeway when HH decides the trailer is too stuffy. He tries to open one of the cute little windows, but it seems they are just for show, not actual windows.

Moments later, SK pulls a lever and an acid bath washes over HH. The screaming lasts only a few moments - not that it matters, since the trailer is very well sealed. The acid sloshes back and forth in the trailer until 19 minutes later when a timer goes off in the cab. SK pulls another lever and the acid is pumped into a holding tank. 10 minutes later, SK pulls another lever, and within a minute he flips all levers back to their original position.

Finally, he presses a button. A red light blinks five times, then turns green.

SK pulls off the exit ramp and into the parking lot of a fast food restaurant. He opens the trailer - holding his breath against the wave of chemical smell - to find HH's clean, bleached bones curled into a tidy fetal position. He uses pliers to pop out the five teeth with dental fillings, and pockets the teeth.

SK scoops the bones into a surprisingly small bag, and tosses the bag into the fast food restaurant dumpster. He drives away.
