Panzram's sentence. Panzram later claimed that while he had been a rotten egg before imprisonment at the military pen, any shred of goodness left in him was smashed out during his Leavenworth stint. After his release and dishonorable discharge, Panzram resumed his career as a thief. Stealing items that ranged from bicycles to yachts, he was caught and imprisoned multiple times. He served prison sentences both under his own name and various aliases in: Fresno, California; Rusk, Texas; The Dalles, Oregon; Harrison, Idaho; Butte, Montana; Montana State Prison (as "Jeff Davis" #4194 #3194 and "Jefferson Rhodes" #4396); Oregon State Prison ("Jefferson Baldwin" #7390); Bridgeport, Connecticut ("John O'Leary"); Sing Sing Correctional Facility, New York ("John O'Leary" #75182); Clinton Correctional Facility, New York ("John O'Leary" #75182); and Washington, D.C.

By his own admission, one of the few times he did not engage in criminal activities was when he was employed as a strikebreaker against union employees. On one occasion, he tried to sign aboard as a ship's steward on an Army transport vessel but was discharged when he reported to work intoxicated. Escalating violence Panzram claimed in his 1929 autobiography that after escaping from a chain gang sentence at Rusk, Texas, he went to Ciudad Juárez, Chihuahua, Mexico, in the winter of 1910 to try to enlist in the Federales. He took a train to Del Rio, Texas, and got off in a small town east of El Paso. He later claimed to have abducted, assaulted, and strangled a man about a mile from town and then stolen $35 ($566.12 in 2021) from the victim. In the summer of 1911, Panzram, going by the alias "Jefferson Davis", was arrested in Fresno, California, for stealing a bicycle. He was sentenced to six months in county jail, but escaped after thirty days. Panzram later claimed that after his escape, while riding on a boxcar in
