Osceola County Sheriff’s Office detectives Tuesday morning arrested Ross Littlefield, of Kissimmee, and charged him with grand theft.

Last week, Littlefield’s wife, Linda Littlefield, a local attorney, was arrested for grand theft and fraudulent use of a credit card after a client came forward with fraud allegations relating to a trust fund.

Authorities said Ross Littlefield, 45, who co-owns the Littlefield Law Group at 404 Broadway Ave. in Kissimmee with his wife, had oversight over the trust fund and that he was aware of the fraud and authorized payments for the fraudulent charges from the fund.

The investigation began Feb. 16 when the Sheriff’s Office received a complaint against Linda Littlefield. The victim told deputies that in February of 2006, she contacted the law firm to set up a trust to acquire Medicaid for her husband, who suffered from Alzheimer’s disease. Several months later, the trust was established with $40,000. At the time, the attorney told family members they would need to surrender their credit cards and the monthly bills so she could pay the balances from the trust fund.

In February of 2009, the victim’s husband died. In January of this year, the victim began receiving credit card statements for one of the cards. The balance was $14,924, but the victim told authorities she remembers giving Linda Littlefield the cards in 2006 with a zero balance. After further investigation, detectives discovered five unauthorized charges totaling $53,793 on all of the credit cards.

All of the purchases were made online, including office furniture and a trip to Cancun that investigators confirmed Linda Littlefield took in July of 2008. She also used $7,900 from the trust account to pay some of the balances on the credit cards, reports said.

On June 17, Linda Littlefield met with detectives and told them the charges were made by mistake, even though the online transactions required the use of the victim’s husband’s name, address and security code.
