BALTIMORE (AP) — A Maryland woman pleaded guilty on Tuesday to conspiring with a neo-Nazi leader from Florida to plan an attack on the power grid in the Baltimore area.

Sarah Beth Clendaniel, 36, of Catonsville, and her alleged co-conspirator, Brandon Russell, believed that sniper attacks on five electrical substations in greater Baltimore “would serve to break down society,” according to a court filing accompanying her guilty plea.

U.S. District Judge James Bredar is scheduled to sentence Clendaniel on Sept. 3.

Clendaniel was charged last year with Russell, an Orlando, Florida, resident who co-founded a neo-Nazi group called Atomwaffen Division. Russell served five years in prison after pleading guilty to explosives charges that stemmed from a deadly shooting at an apartment that he shared with Atomwaffen’s other founder.

Clendaniel and Russell began exchanging letters around 2018 while they were serving prison sentences in different facilities. They developed a romantic relationship that continued after they were released from prison, the court filing says.
