A Colorado park ranger faces felony charges after investigators say he fabricated a stabbing attack that triggered a massive manhunt and community lockdowns.

A seasonal park ranger was arrested after being accused of lying about being stabbed, Colorado officials said. On Aug. 19, Callum Heskett, 26, called for help from Staunton State Park saying he’d been attacked and stabbed and gave a detailed description of the alleged suspect, according to a news release by Jefferson County.

In fact, the Jefferson County Sheriff’s Office said Thursday, the ranger had injured himself and orchestrated an “elaborate hoax” claiming someone had attacked him and fled.
