Tyler Robinson, charged with killing conservative activist Charlie Kirk, lived a very different life just a few years ago. Friends remember him as a shy gamer with plenty of friends who “never got mad at people.” But after dropping out of college, his life spiraled.

Robinson moved in with Lance Twiggs, a transgender gamer with a troubled past. Family members described Twiggs as “angry” and struggling with addiction and mental health issues. The two began dating, bonding over gaming, and shared a small apartment in Utah.

Investigators uncovered Robinson’s interest in disturbing furry pornography and online forums. They also found messages suggesting Twiggs may have known Robinson was engraving bullets before the murder. “You weren’t the one who did it right????” Twiggs asked in one text.

Adding to the drama, Twiggs allegedly kept a flirty friendship with another man, fueling speculation about tension in the relationship. As police question both separately, many wonder whether their dark relationship holds the key to understanding Kirk’s shocking assassination.
