Sam and Tolki were a married couple who ran the popular twitch stream "ShowVideoGames". They were most famous for their long marathons and interaction with their viewers. ShowVideoGames (SVG) was at its peak midway through 2014, in which Sam and his wife Tolki decided they were going to attend a charity event in Denver called SGDQ (summer games done quick).
We have only bits and pieces of information, but what we know for certain is that some point during SGDQ Tolki had sex with Stivitybobo (another twtich streamer).
Information leaks suggest that during SGDQ on the 26th of june at around 3am, Tolki was given alcohol. Sam didn't start drinking since he was a devout mormon, and he insisted Tolki stop as she became drunk and flirty with Stiv, but Tolki refused to listen to him. Sam left the room and later that night tolki cheated on sam with stiv and the 2 other streamers they were rooming with.
when sam found out the next morning, he was reported to have left the hotel to drive back to Utah from Denver by himself. Some time after that, Stiv was reported to have had sex with her in the hotel room. Sam never came back for Tolki and she ended up having to get a plane ticket home.
There are other unconfirmed eye witness reports that after Sam's departure Tolki had sexual relations with up to 20 different men. Regardless of what actually did or didn't happen, no one heard from either of them until Sam posted on the official SVG twitter exactly 2 years later.
