The Howard Schultz Tapes are a series of documentations by a teenage boy before he went missing. Many believe this tape solves his disappearance entirely. The tapes were posted to twitter.com over a period of 3 months. They documented his feelings towards Starbucks CEO and possible presidential canditate Howard Schultz, as well as support for Beto O'Rourke at times. It's speculated that Starbucks had an actual hand in his mental state at the time, for reasons we'll touch on later.
Theorists often discuss the how the teen changes throughout the tapes, so for your convenience I've made a chart noting his changes throughout the tapes.
