US identifies remains of 2 soldiers returned from North Korea after Trump summit
Army Cpl. Jerry M. Garrison and Sgt. Gerald B. Raeymacker were reported missing within a few days of each other in December 1950 in North Korea.
North Korea returned 55 cases containing the remains of US service members in July 2018, after President Donald Trump's summit with North Korean leader Kim Jong Un.
The Defense POW/MIA Accounting Agency (DPAA) has identified the remains of 35-40 service members that were in those crates, said DPAA spokesman Sgt. 1st Class Sean Everette.
The agency doesn't yet know how many people's remains were in the crates, Everette said.
"Our labs are continuing to identify as many of the remains as we possibly can," he said.
The DPAA says that 7,609 Americans remain unaccounted for from the Korean War.
Both Garrison and Raeymacker died in the Battle of the Chosin Reservoir, one of the war's bloodiest battles. US Marines and soldiers were advancing toward the Chinese border when more than 100,000 Chinese soldiers poured over the border, surprising US Marines of the 1st Marine Division, soldiers from the Army's 31st Regimental Combat Team and South Korean and British units.
Surrounded by the Chines, US and allied forces were forced to fight their way to way to safety during one of North Korea's worst winters. After the two-week battle, nearly 6,000 Americans were dead or missing and the Chinese lost an estimated 50,000 soldiers.
