New details have emerged about the alleged shooter of Charlie Kirk — and his transgender partner. Lance Twiggs, 22, reportedly shared posts praising President Biden and frequently engaged in online discussions about gender transition.

Twiggs, who went by “Lancelotte” online, was allegedly in a romantic relationship with suspect Tyler Robinson, also 22. According to police, Twiggs cooperated with investigators and handed over incriminating texts, including messages about hiding a gun and engraving bullets.

Robinson, an avid gamer using the username “Craftin247,” was also linked to a furry website where he registered just two months before the shooting. One bullet recovered at the scene had the phrase, “Hey fascist! CATCH!” engraved — a chilling reference, investigators say, to his motive.

Police are examining whether Kirk’s outspoken comments on transgender issues triggered the attack. Robinson faces multiple charges, including aggravated murder, and will appear in court Tuesday.
