WARSAW, Poland—Polish prosecutors have ended an investigation into human skeletons found at a site where German dictator Adolf Hitler and other Nazi leaders spent time during World War II because their advanced decay made it impossible to determine the cause of death, a spokesman said Monday.

The remains were found Feb. 24 at Wolf’s Lair, which served as Hitler’s chief headquarters from 1941–1944 when the area was part of Germany. The compound of about 200 Nazi bunkers and military barracks hidden in deep woods was the site of the failed assassination attempt on Hitler by Col. Claus Stauffenberg on July 20, 1944. The site is now a tourist attraction.
