Animal control officers in Sioux City, Iowa, say someone dressed a dead deer in a clown suit and wig and put it on a family's porch.
Officers suspect it was a prank, considering Halloween is approaching, but they say it's not funny, safe or acceptable.
The deer was discovered Wednesday morning.
Animal Control Officer Jake Appel says leaving a dead animal is immature and illegal. He says officers will dispose of the deer properly.
Sioux City police have not opened an investigation.
