Bindi Dhanji went missing before sentencing was due to take place at Southward Crown Court on Tuesday.
She had previously confessed to stealing more than £100,000 from two elderly bank clients.
The Metropolitan Police Service says two bodies were found yesterday morning hanging from a bridge over the A406 at Staples Corner, but that the bodies have yet to be formally identified.
A spokesman says: “We believe we know the identities, but we are waiting for formal identification.”
A post mortem is due to take place tomorrow.
