SANTIAGO, Chile (AP) — The case of a U.S. hiker who disappeared during Chile's dictatorship has finally resulted in arrest warrants.

Judge Jorge Zepeda ordered the arrests Tuesday of eight former police and military officials on charges of kidnapping and conspiracy to cover up the disappearance of Boris Weisfeiler. He was a Princeton University professor who hasn't been seen since 1985.

The indictment says Weisfeiler was wearing military-style clothes while hiking alone near the Argentine border and the officers suspected he was a leftist militant sneaking into Chile to challenge the regime of Gen. Augusto Pinochet.

It says most of the evidence came from declassified U.S. files. They include witness accounts of how Weisfeiler was kidnapped and delivered to Colonia Dignidad, a German enclave that Pinochet's secret police used as a torture center.
