Other Personnel In Incident: Robert E. Pietsch (missing)


SYNOPSIS: Maj. Luis Guillermin and Lt.Colonel Robert Pietsch were flying an
A26A aircraft over Laos when their plane was downed in Savannakhet Province,
Laos.  Their last known location was about 10 miles east of the city of Ban
Muong Sen.

The A26A was redesignated B-26 following World War II and then given its
original classification as an attack plane.  After some resesigning for
counterinsurgency warfare and changes in armament, the craft was rechris-
tened A-26A.  The aircraft could remain on station for a long time,
patiently searching ot and attacking an enemy concealed by jungle in night
or bad weather.

The fates of Guillermin and Pietsch are unknown.  There are among nearly 600
Americans who disappeared in America's "secret war" in Laos who never
returned.  There is ample reason to believe that the Vietnamese and/or the
Communist Lao know what happened to Guillermin and Pietsch on April 30,

There have been over 5000 reports given to the U.S. Government relating to
Americans held captive in Southeast Asia.  The U.S. has, thus far, been
unable to find the formula to bring them home.  One of them could be Louis

Missing Airmen From Vietnam War Accounted For
The Department of Defense POW/Missing Personnel Office (DPMO) announced today that the remains of two U.S. servicemen, missing from the Vietnam War, have been accounted for and will be returned to their families for burial with full military honors.

U.S. Air Force Lt. Col. Robert E. Pietsch, 31, of Pittsburgh, Pa., and Maj. Louis F. Guillermin, 25, of West Chester, Pa.,will be buried as a group Oct. 16, in a single casket representing the two servicemen at Arlington National Cemetery, near Washington, D.C.  Guillermin's individual remains weres buried Oct. 5, 2013, in Broomall, Pa. 

On April 30, 1968, Guillermin and Pietsch were on an armed-reconnaissance mission when their A-26A Invader aircraft crashed in Savannakhet Province, Laos.  Witnesses saw an explosion on the ground and did not see any signs of survivors.  Search and rescue efforts were unsuccessful, and Guillermin and Pietsch were listed as Missing in Action.

 In 1994, a joint U.S./Lao People's Democratic Republic (LPDR) team, lead by the Joint POW/MIA Accounting Command (JPAC), surveyed the crash site in Savannakhet Province, Laos.  The team recovered human remains and evidence, but was unable to fully survey the site due to the presence of dangerous unexploded ordinance. 

In 2006, joint U.S./LPDR teams assisted by Explosive Ordnance Disposal personnel cleared the site and gathered additional human remains and evidence, such as personal effects and crew-related equipment.

The remains recovered were analyzed by scientists from JPAC and the Armed Forces DNA Identification Laboratory using circumstantial evidence and forensic analysis, such as mtDNA comparisons. Portions of the remains were individually identified as Guillermin through an mtDNA match from a hair sample from Guillermin's medical file.  The rest of the remains recovered were not individually identified, but correspond to both Pietsch and Guillermin.

There are more than 1,640 American service members still unaccounted-for from the Vietnam War.  




Return to Service Member Profiles

On May 28, 2013, the Joint POW/MIA Accounting Command (JPAC, DPAA) identified the remains of Major Louis Fulda Guillermin, missing from the Vietnam War.

Major Guillermin entered the U.S. Air Force from Pennsylvania and was a member of the 609th Air Commando Squadron. On April 30, 1968, he was navigator aboard an A-26A Invader that carried one other crew member on an armed-reconnaissance mission to enemy targets in Laos. While over the Savannakhet Province, the Invader was shot down by enemy fire, killing Maj Guillermin. His remains could not be recovered at the time. In 1994, a joint U.S./Laotian team surveyed the crash site and recovered human remains but was unable to fully survey the site due to unexploded ordnance. In 2006, explosive ordnance disposal personnel cleared the site, and the team was able to gather additional evidence. Modern forensic technology was eventually able to identify Maj Guillermin among the remains recovered. 

Major Guillermin is memorialized in the Courts of the Missing at the National Memorial Cemetery of the Pacific.
