In June 2020, a group of teens from Seattle were using a TikTok app called Randonautica, which sets users out on outdoor adventures by giving them a random set of coordinates to explore.
It was a Friday evening when the app sent the teens to a certain location along the waterfront at Duwamish Head, Washington.
While filming in real time, the TikTok users came upon an abandoned black suitcase that had washed up onto the rocks.
At first, they hoped they'd find a hidden treasure inside. But as one of the teens carefully lifted the top of the suitcase using a stick, an overwhelmingly foul stench filled the air.
Scared and concerned, the TikTok video then showed another teen calling 911 as police arrived.
Watch the video to see how this horrifying discovery unfolded — and just what was found inside that abandoned suitcase.
