Kabul , Afghanistan ( CNN ) -- Military divers have found the body of a U.S. paratrooper who went missing last week in a river in western Afghanistan . The NATO-led International Security Assistance Force said the soldier was found close to where he disappeared November 4 . Officials are continuing their search for a second paratrooper lost at the same time . Both men -- from the 4th Brigade Combat Team , 82nd Airborne Division -- disappeared in the Morghab River near Afghanistan 's border with Turkmenistan . The men were on a routine resupply mission , the NATO group said . Family members identified the recovered body as that of Benjamin Sherman , 21 , of Plymouth , Massachusetts . They said he jumped into the river when he saw a fellow soldier struggling in the water . `` I know that day he jumped into the river to try to save his comrade was because he did n't just see another soldier in the water ; he saw his brother , '' said Sherman 's sister , Meredith , in a statement to CNN affiliate WCVB in Boston , Massachusetts . `` He did n't jump in because he was trained to but because that 's what his heart told him to do . '' Sherman 's mother , Denise , said the family called him `` the unstoppable one . '' `` I raised him with the understanding that when you choose to do something , you do it to the best of your ability , '' she said in a statement to WCVB . `` He was powerful , ingenuous and determined . '' CNN 's Thomas Evans contributed to this report .
