The Rogers County Sheriff's office is looking for Mark Pace, who is wanted for draining the bank account of an elderly woman with dementia.
Police say Pace was working with his mother, Dorothy Allen.
She turned herself in and has bonded out of jail.
They say the pair got a woman to sign checks, thinking they were buying items like groceries, but instead the checks were cashed for thousands of dollars.
"They, in fact, bought a Corvette with this lady's money that belonged to her, and no way would this lady have a need for a Corvette," Rogers County Sheriff Scott Walton said.
Records show Pace and Allen drained nearly $40,000 from the victim's account.
Investigators worry there may be additional victims are out there.
