NEW: Kirk Assassin Tyler Robinson’s Trans Lover Has ‘Vanished’

Neighbors living near the lover of Charlie Kirk’s suspected killer say the transgender person has vanished after vacating their townhouse, leaving nothing but questions about their whereabouts.

Lance Twiggs, who was living with Tyler Robinson, 22, when he allegedly carried out the assassination of Kirk on Sept. 10, is no longer living at the couple’s Utah residence. A reporter who visited the property on Tuesday noted a stack of unopened mail near the front door.

The biological man living as a woman is being investigated as a potential co-conspirator after Robinson opened fire on a Utah college campus, killing Kirk with one shot to the neck. Robinson allegedly confessed to Twiggs in a string of text messages where he asked his lover to promise not to share the messages or speak with authorities.

Mail was seen piling up outside the $1,800-a-month townhouse where police presence is still felt in the neighborhood two weeks after the slaying.

Jesse Riley, who lives just several doors down from the property, said he has seen no sign of activity there in days.

“It definitely is a shock it happened here. It’s a quiet neighborhood. You know your neighbor on your left or your right, but people are pretty isolated,” he told the NY Post.

“I haven’t seen anyone come out. There are still all these notes on the door, so it looks like nobody has been in there.”

Washington County Sheriff Nate Brooksby previously told the outlet that Twiggs was in a “safe space very far away from St. George,” and needed “to lay low for a long time.”

Twiggs has not been charged in connection with Kirk’s murder, while Robinson faces the prospect of a death penalty conviction after being charged with aggravated murder, obstruction of justice, and witness tampering.

A note left underneath Twiggs’s keyboard appears to lay out Robinson’s reasoning for targeting Kirk, a conservative activist and founder of Turning Point USA, whom Robinson accused of “spreading hate” on college campuses, the NY Post reported.

Family members of Twiggs have described him as the “black sheep” who was kicked out of his parents’ house after refusing to give up drugs and video games. Other messages exchanged by Robinson with online gamers, plus notes left at the scene of the shooting, suggest he was very much involved in gamer culture as well.

Twiggs lived with his grandparents before moving in with roommates. Robinson moved in several months later, and they both quickly moved into a romantic relationship
