Ex-roommate of CEO murder suspect stunned by accusations

The former roommate of Luigi Mangione, the alleged murderer of CEO of UnitedHealthcare Brian Thompson said he “felt strange” about the Ivy League graduate's arrest because he knew someone who was “completely different.”

RJ Martin told “Jesse Watters Primetime” on Tuesday that he was roommates with Mangione for six months at Surfbreak Coliving in Honolulu, a “self-described coworking space for remote workers and digital nomads.”

“All the time he [Mangione] lived in Surfbreak, he was a wonderful community member. He somehow followed by our values and our ethic to leave things better than you found them. He was always contributing, taking care of others. And even after he moved, he came to hang out and contribute to the community, running a book club,” Martin said.

“He's the kind of guy who was doing his best to take care of himself despite having severe back pain and, you know, a serious problem,” Martin told Fox News host Jesse Watters.
