Case from 2019 (U.S. Attorney's Office release: March 18, 2019). Published on Scammers.com Oct. 16, 2026; case status is current as of that date.
John V. Knapp of Romeoville, Illinois, was sentenced on March 15, 2019, to four and a half years in federal prison for stealing his elderly mother-in-law's identity to take more than $175,000 from her accounts, the U.S. Attorney's Office for the Northern District of Illinois announced [1]. He was ordered to pay $177,538.38 in restitution.
How the scheme worked
According to Knapp's plea agreement and evidence described by prosecutors [1]:
- Family access: In 2014 and 2015, when his mother-in-law was in her mid-90s, Knapp took money from her investment and bank accounts on about 100 occasions.
- Impersonation by phone: On four calls to her investment company he posed as her, giving her address, date of birth, phone number, account number and partial Social Security number to authorize $129,500 in withdrawals.
- Cashing out: Once the money reached her bank account, he caused checks to be written to himself.
- Timing: During one call she was in a hospital; during two others she was living at a rehabilitation center.
The person sentenced
John V. Knapp, 66 at sentencing, of Romeoville, Ill. [1]

Red flags
- A relative or caregiver who insists on handling all calls with an older person's bank or investment firm.

What to do if you're targeted
- Ask financial institutions to add a "trusted contact" and require in-person or video verification for withdrawals.
