Haynes, 57, formerly of Spring Lake, was charged in May as a part of the Michigan Attorney General's Elder Financial Crimes Unit. He was prosecuted by the Muskegon County Prosecutor's Office.
The victim in the case paid a fee to attend a financial planning seminar led by Haynes in 2006. The woman asked Haynes to help her pay her bills with computerized billing systems.
The 85-year-old woman was recently widowed and no children. She gave Haynes access to her computer, financial accounts and passwords.
Haynes acted as the woman's agent for 10 years and he used their relationship to influence her financial decisions and to take her money for his advantage. Haynes was found guilty of using the woman's money for his company Senior Planning Resource and Future.
The woman also says she gave money to Haynes to invest, but that is not what Haynes did with the money.
Over the course of four years, Haynes transferred over $300,000 from the woman's accounts to bank accounts that belong to his two companies. The attorney general's office also says that Haynes' tax returns did not accurately reflect the amount he stole.
In 2016, the woman became suspicious about the money she asked Haynes to invest and asked him about it. The information was then reported to LARA who referred the case to the attorney general.
Haynes will be sentenced on Feb. 8, 2019.
