A northwest Arkansas teenager thought it would be funny to text a random phone number saying she hid a body, but the joke backfired.

Of all the local phone numbers she could have chosen, the 15-year-old Rogers girl picked one that belonged to a police detective. Police found the girl’s address by tracing her cellphone number.

The prank? To text: “I hid the body … Now what?’’ to a random phone number. The teen said she got the idea for the prank from a posting on the website Pinterest.

Police didn’t find the prank funny and say it tied up some of the department’s resources.

The girl was released with a warning.
