The man who fatally shot a security guard at the United States Holocaust Memorial Museum had the address of a Member’s Congressional office, Senate Sergeant-at-Arms Terrance Gainer said Thursday.

Gainer declined to name the Member or say where the address was found.

James W. von Brunn, an 88-year-old known white supremacist, entered the museum Wednesday afternoon and allegedly shot security guard Stephen Tyrone Johns before being shot by two other guards.

Johns died, and von Brunn remains in critical condition.

In the hours after the incident, several media outlets reported that von Brunn had a list of other targets. A couple of outlets also reported that he had a list of Members’ names.

But Gainer dispelled those rumors, writing in an e-mail that “to our knowledge there is no list of Members who were targeted by the Holocaust shooter.—

However, he added that von Brunn did have the “business address— of a Member. He said the address was of a Congressional office, but he declined to provide any additional details.

“There was one business address of a Member; but nothing else,— he said in the e-mail. “We know of no threats against Members; we continue to work with federal partners and monitor the investigation and remain in the intelligence loop. He appears to be a lone, trouble[d], hateful actor.—

At a Thursday press conference, FBI official Joseph Persichini also denied that von Brunn had a list of targets at all; instead, he said, police found various “materials— in von Brunn’s car.
