An ex-chief financial officer for Dallas-based Service King Collision Repair Centers was sentenced to three years in prison for his role in embezzling more than $2 million in funds from the business and company owner.

61-year old Daniel L. Mangini of Southlake was sentenced Monday after being convicted of mail fraud in what federal investigators say was a theft scheme that ran from 2006 to 2012.

Prosecutors say Mangini was also the personal certified public accountant for Service King owner Edward Lennox.

Investigators say Mangini had access to the owner’s accounting system and printed or wrote unauthorized checks to himself, then mailed the wrongful funds to creditors.

As a particular example, Mangini admitted in January 2012, he wrote a $40,000 check payable to American Express from one of Lennox’s accounts.  Mangini admits the check was not authorized and that the money was embezzled from Lennox.  To conceal the scheme, Mangini backdated the check by one year in Lennox’s records.

Mangini must also forfeit his luxury million dollar beachfront home in Destin, Florida – part of the $2,459,218 he was ordered to pay in restitution.
