There is a claim circulating that Robinson had a transgender/transitioning (MtF) roommate/partner. A simple web search will easily find multiple sources for this claim, but most of them aren't exactly what you'd consider authoritative or journalistic.
Many sources similarly assert that Robinson's father "recognized" him in photos and "encouraged him to turn himself in" (see e.g. https://www.washingtonpost.com/opinions/2025/09/12/tyler-rob...). However, I don't know anything specific about his "testimony".
