Prosecutors say four North Texas relatives have been accused of faking mental illness to get government benefits in a scam since 1978.
Doreen Mitchell, her two sons and her cousin face detention hearings Friday in Dallas.
The 55-year-old mother, 29-year-old Michael Mitchell, 27-year-old Sonny Mitchell and 58-year-old John Mitchell, also known as Patrick Rena, were arrested this week.
A complaint says the Arlington residents are charged with conspiracy to defraud the Social Security Administration of nearly $462,000. Doreen Mitchell began receiving benefits in November 1978.
Records show officers followed Doreen Mitchell in 2014 as she drove, shopped and scrolled through her cellphone. She attended a benefits revocation hearing days later and mumbled, appeared disheveled and said she couldn't leave the house alone.
Court records don't list attorneys for the Mitchells.
