German news agency dpa reports that a woman at the center of a high-profile neo-Nazi murder trial worked for an informant of Germany's domestic intelligence agency while she was on the run from police.

Dpa reported Thursday, without naming its source, that Beate Zschaepe worked in a store in the eastern town of Zwickau. German daily Die Welt reported separately that store owner Ralf Marschner also employed co-conspirator Uwe Mundlos, who died together with the self-styled National Social Underground's third member following a botched heist in November 2011.

Both media said Marschner supplied information to the BfV intelligence agency, leading to questions about why the three weren't apprehended. The agency said it couldn't confirm the media reports. Its chief resigned in 2012, months after the NSU's existence came to light.
