HOUSTON (CBSDFW.COM) — Deputies with the Harris County Precinct One Constable’s Office say a man has been terrorizing a neighborhood in the Woodland Heights area of Houston by going to the bathroom in several yards at night.

“We’ve had reports from six to eight neighbors out there that someone is actually coming into their yard and defecating — generally on their driveways,” said Sgt. J.C. Mosier.

Authorities believe the unknown man is committing the act between 1:00 and 4:00 a.m., but a motive for crimes has not yet been established.

“I think the neighbors are laughing about it, but that’s because it’s only happened to two houses in the neighborhood. If it starts happening more, I think people might become enraged,” says Amy, who lives in the Heights. “How much poop can one man make though?”

She says one person’s house has even been hit as many as six times.

“I’m thinking revenge poop is definitely a possibility. We’re all wondering, what did this person who’s having the creep-crapper hit their house repeatedly do?”

Sgt. Mosier agrees that revenge could be the motive, as he recalls a similar event many years ago in the Houston area.
