Suspect Arrested in Arson Attacks on New Mexico G.O.P. Office and a Tesla Dealer

An Albuquerque man was arrested on Monday in connection with the fire bombings of the Republican Party of New Mexico’s headquarters in March and a Tesla dealership in February, attacks that the federal authorities have designated as “domestic terrorism.”

The suspect, Jamison Wagner, 40, had parked his white Hyundai sedan at both locations before the arson attacks and then drove away, according to security and traffic camera images released by the Justice Department.

Federal prosecutors said that surveillance footage from the Tesla showroom near Albuquerque on Feb. 9 showed him carrying a box of supplies that he used to spray-paint graffiti on the building and several vehicles. Investigators said that he had scrawled the phrases “Die Elon,” “Tesla Nazi Inc” and “Die Tesla Nazi,” references to the company’s billionaire founder, Elon Musk, who is leading the Trump administration’s cost-cutting program. Mr. Wagner was then observed breaking some car windows and throwing an incendiary device inside one of them, destroying it, a criminal complaint said.

Several weeks after that arson attack, the authorities said, Mr. Wagner struck again, torching the lobby of the Republican Party of New Mexico’s headquarters during the early morning hours of March 30.

Investigators say that he left behind critical evidence each time, connecting him to both crimes: lids from a jar of Smucker’s jelly and a container of olives that they said he had filled with gasoline. Both lids had the letter “H” or “I” written on them with what appeared to be a marker, photographs showed.
