PITTSBURGH (AP) – Federal authorities say remains of an American soldier killed during the Korean War have been accounted for and will be interred at Arlington National Cemetery. The Defense POW/MIA Accounting Agency said Monday it verified the remains of 28-year-old Army 1st Lt. Robert C. Styslinger of Pittsburgh in August. It says his remains were among 55 boxes turned over by North Korea in July 2018, after a summit between President Donald Trump and North Korean leader Kim Jung Un. Styslinger was reported to have been killed in action in November 1950 in North Korea.
