A retired Navy skipper who successfully petitioned for documents delving into the deadliest submarine disaster in U.S. history says he's satisfied there was no coverup.

Utility workers and wildlife managers across the Pacific Northwest were trying to keep people and animals safe as a historic heat wave scorched the region and sent residents searching for relief.

The first of the documents released were 300 pages from the official inquiry into the sinking of the USS Thresher on April 10, 1963. The crew of an accompanying rescue ship heard something about the “test depth.” Then the sailors listened as the sub disintegrated under the crushing pressure of the sea. The documents released Wednesday included the timeline of the sinking, evidence lists, reports, testimony and correspondence. Even more than 50 years later, technical details including the test depth were redacted. His suspicion is that the Navy was pushing the limits and placing personnel at risk during the Cold War.

DETROIT Police are asking for help locating a missing 29-year-old man last seen Saturday afternoon. Bryant is 5 feet, 11 inches tall and weighs about 160 pounds. He was last seen wearing a blue shirt, gray pants and Nike Air Force 1 Shoes. He is reportedly in good physical condition but his mother said he may try to harm himself. Anyone with information is asked to contact Detroit Police Department at 313-596-5740 or Crime Stoppers at 1-800-Speak-Up.
