After receiving $500,000 in ransom money, he was captured and sentenced to life in prison in 1969, but was released on parole after 10 years and went on to commit several more crimes.

[4] Krist was paroled after serving 10 years and granted a pardon after he was accepted to medical school at the Autonomous University of Guadalajara in Mexico so that he could become a physician.

When he returned on March 6, 2006, authorities were waiting for him and discovered four undocumented immigrants, who paid $6,000 each to come to the United States, and 14 kilograms of cocaine in paste form valued at around US$1 million.

On May 16, 2006, Krist pleaded guilty to drug smuggling; and, on January 19, 2007, he was sentenced to five years and five months in prison at the Federal Correctional Institution in Marianna, Florida.

[7][8] On August 27, 2012, in Mobile, Alabama, U.S. District Judge Callie V. Granade revoked Krist's supervised release for violating his probation.
