If Perrigo was, in fact, cremated it would have been in accordance with the expressed wishes of his designated surviving next of kin. The procedure was usually performed by a private crematory, under contract with the Army, as soon as practicable after the remains arrived in the United States. The cremated remains, escorted by an Officer or Staff Non-commissioned Officer, were then forwarded by train to the mortuary designated by the surviving next of kin.
An example: Captain Benjamin Louis Salomon, Jr. (aka Ben L. Salomon), 0 489 134, who was killed in action at Saipan on 9 July 1944 (he was later awarded the Medal of Honor posthumously), was interred in the 27th Infantry Division Cemetery at Saipan on 11 July 1944. He was exhumed 15 March 1948 and prepared for shipment three days later. Shortly after arrival at San Francisco Port of Embarkation/Entry (SFPE), Oakland Army Base, Oakland, according to the sworn affidavit of First Lieutenant Winfred E. Patterson, Transportation Corps, representing the Chief, American Graves Registration Division, SFPE, on 25 May 1948, Salomon's remains were cremated and inurned at Chapel of the Chimes Crematory, 4499 Piedmont Avenue, Oakland. The urn, escorted by Technical Sergeant Harlan T. Smith, was then shipped, aboard Union Pacific Train Number Fifty-eight, to Mailnow & Simons Mortuary, 818 Venice Boulevard, Los Angeles, and arrived in Los Angeles at approximately 9:10 a. m., 30 June. The urn was placed in a niche with the remains of his mother, Rebecka Leszinsky Salomon (aka Bess L. Salomon), in the columbarium at Forest Lawn Memorial Park in Glendale.
