On Monday, former Gulfstream executive Marvin Jay Caukin was sentenced to just over 11 years (135 months) in prison after a conviction for conspiracy to commit mail fraud.

Caukin embezzled more than $10 million from Gulfstream from 2001 to 2013, according to court records. He was hired in 2000 as the director of finance and accounting for Gulfstream Aerospace and, according to the original criminal complaint, created “fictitious business invoices”, which Caukin would then approve in order to confirm payment in the form of checks. Those checks were then mailed to rented mailboxes and deposited into bank accounts of bogus companies set up by Caukin.

This was not Caukin’s first fraud conviction. He served a three year prison sentence in the early 1990s for a similar charge.

In addition to prison time, Caukin, who entered into a plea agreement with prosecutors in early January, has been ordered to pay over $10 million in restitution.
