In 2005 , U.S. Representative Eliot Engel , whose district includes Pearl River , introduced a bill in Congress to officially rename the post office after Heinz Ahlmeyer , a native who had joined the Marine Corps as a second lieutenant after graduating from SUNY New Paltz . On Ahlmeyer 's first day of service in Vietnam in 1967 , leading a Long Range Reconnaissance Patrol unit along the Ho Chi Minh Trail near Khe Sanh , he was reported to have been killed ; however , due to heavy small arms fire his body could not be retrieved at that time . They were identified in 2005 and he was buried with full honors at Arlington Cemetery . It became the second Register-listed post office in the county to be named in honor of a deceased local resident , after the 2004 renaming of the Nyack post office in memory of police officers slain in the 1981 Brinks robbery
