ST. GEORGE, Utah – The trans roommate of Turning Point USA Founder Charlie Kirk’s alleged assassin “hates conservatives and Christians,” one of his relatives told Fox News Digital in an interview.

The 22-year-old, who has not been charged and whose name has not yet been released by authorities, was in a romantic relationship with suspect Tyler Robinson, also 22, according to the relative. She said he is in the process of transitioning from male to female.

The woman, who asked to remain anonymous, told Fox News Digital her relative began to act differently when he turned 18 and said that he developed a hatred of Christians and conservatives.

“Everybody in my family wants justice to be served and wants no part in this and wants whoever is involved in whatever way to have to pay for that,” the relative added.

Fox News Digital was told by an FBI official that Robinson’s roommate has been “extremely cooperative” and “had no idea” about Robinson’s alleged plans to assassinate Kirk.

Robinson and his roommate shared an apartment in St. George, Utah, where both of their families reside.

It was Robinson’s father who turned him into authorities after he recognized his son in surveillance videos that the FBI released, a law enforcement source earlier told Fox News Digital.
