(From L to R) Capote, Al & Marie
Alvin was born September 10, 1912 in Kingman County, Kansas. He started with the Garden City Police Department in June of 1936 for a salary of $60 a month. He later attended San Jose State College in California majoring in police administration; and in 1939, he became a state trooper with the Kansas Highway Patrol. In 1940, he became a special agent with the FBI, being sent to New Orleans, Louisiana, as his first assignment. There, he met Marie Louise Bellocq, and FBI stenographer who became his wife June 28, 1942. For the next three years, Agent Dewey travelled with his family to Texas, Florida and eventually Colorado.


In 1945, he took a year’s leave of absence from the FBI when he and Marie came back to Garden City, Kansas. Due to his father’s illness, he was temporarily helping his mother in the operation of the Blue Bird Cabin Camp. That year, he was approached by the Democratic Party to run for office of Sherriff for Finney County. He won the election, resigned from the bureau, and served in that office for nine years until becoming a Special Agent of the KBI in 1955. While Sherriff, Dewey enlisted in the Kansas National Guard.
The only time Al Dewey smiled during the whole investigation was when he announced Hickock and Smith were ARRESTED!
Over the next three years, Marie gave birth to both of their sons, Al the 3rd and Paul.
As the result of the successful investigation of the Clutter murder case, Dewey was requested by the U.S. Senate Committee on the Judiciary to appear before the Subcommittee on Constitutional Amendments in Washington, D.C. to discuss his opinion of the Supreme Court’s decision in the case, Miranda v. Arizona. He disagreed with the decision of the case and outlined how adversely that decision would have affected the solving of the Clutter case.
In his memory, Marie established the Alvin A. Dewey Memorial Scholarship Fund at Garden City Community College in the Criminal Justice Department.
