CORAL GABLES, Fla.- A South Florida caregiver is accused of swindling an 86-year-old woman with dementia out of almost $1 million.
Investigators say 39-year-old Marie Petit Louis was arrested Tuesday following a two-year investigation that began shortly before Annette Reff died in 2012. She's charged with exploitation of the elderly in a complicated bank transfer scheme.
Reff's daughter notified authorities after noticing large chunks of money missing from her savings account.
The Miami Herald ( ) reports investigators learned Petit Louis instructed investment officials to transfer money from several accounts into a savings account. They say she accompanied Reff to the bank numerous times, withdrawing amounts under $10,000.
Petit Louis was a regular at Miami's Magic City Casino and a member of the High Roller's Club.
It was unclear whether she's hired an attorney.
