Captain Arman was shot and killed November 1, 1927 when he investigated an armed robbery in progress at the Tippecanoe Loan and Trust Bank. About $1,000 was taken by 6 armed robbery suspects. As Captain Arman entered the bank, he was shot 3 times and died at the scene of the shooting. The suspects escaped in a car with Iowa license plates.
Police were able to later identify 2 of the 6 suspects, 1 escaped from prison while serving a 25 year sentence, but was later paroled and has since died. The other suspect committed suicide in Sidell, Illinois following the robbery of a Clinton, Indiana bank in 1930, in which 2 other men suspected in Captain Arman's murder were also killed. Of the remaining suspected individuals, 1 was recaptured 3 days after the same prison escape while another was killed by police during their recapture.
