Add to My HeroesThomas Eric Gahl
Probation Officer Thomas Gahl was shot and killed while attempting a home contact in Marion County, Indiana, at the residence of a newly-released probationer with a life-long history of mental illness.
The purpose of the visit was to obtain a urine specimen to determine whether the probationer had been taking drugs. Before Officer Gahl could do so, he was struck with three shotgun blasts by the offender in an unprovoked attack.
At the time of the shooting, Officer Gahl, like other officers in his district, was not armed. While being pursued during the manhunt that followed, the offender's crime spree included two other murders and several kidnappings before ending with the offender committing suicide.
Officer Gahl was a United States Marine Corps Vietnam War veteran and had served with the United States Probation Office for the Southern District of Indiana for 11½ years. He had previously served with the Indiana Department of Correction, the Federal Bureau of Prisons. Officer Gahl was survived by his wife, two young sons, brother, and mother.
On June 24, 1994th, the Thomas E. Gahl United States Probation Office was dedicated at the Indianapolis, Indiana, headquarters in his honor.

View all 30 ReflectionsI am a retired U.S. Probation Officer, and the curator of our national Museum. I’ve had the pleasure of meeting and working with the Gahl family. They have sacrificed much to continue to try to keep our officers safe. There’s a page on the museum website, devoted to Tom, including his badge, credentials and the wanted poster for his murderer. Tom will always be a part of our systems collective consciousness and we value the family he left behind.
