BERLIN (AP) -- German prosecutors are indicating that a new investigation into a deadly far-right attack 35 years ago on Munich's Oktoberfest beer festival has made little progress, with testimony from a new witness failing so far to stand up.
Federal prosecutors pledged to pursue all leads anew a year ago after the witness surfaced.
Thirteen people were killed and more than 200 wounded in the bomb explosion Sept. 26, 1980. The dead included the attacker, student Gundolf Koehler, a supporter of a banned far-right group.
Investigations were closed in 1982 but prosecutors said last year the new witness's testimony may point to previously unknown co-conspirators. However, they said Friday her evidence wasn't substantiated by questioning of witnesses and a search. Other questioning hasn't yet produced a "coherent overall picture."
The investigation continues.
