Dive searches were conducted in areas identified by side-scan sonar, both in the morning and afternoon, yet no new information has surfaced after the CV-22 Osprey aircraft crashed on Wednesday, the 10th Regional Coast Guard told ABC News.

At least one U.S. airman who had been onboard the aircraft was recovered from the ocean and later died, Japanese officials said.

The airman was identified by the Air Force on Friday as Staff Sgt. Jacob "Jake" M. Galliher, 24, a direct support operator assigned to the 43rd Intelligence Squadron.
