ST. LOUIS (AP) — A woman has been sentenced to a year and a day in prison after federal prosecutors said she hid her mother’s death from the Social Security Administration for 20 years and kept $185,000 in retirement benefits.

Mildred McClimans-Ratliff, 46,  was sentenced Thursday after pleading guilty to three counts of theft of government funds.

Prosecutors said McClimans-Ratliff began spending her mother’s Social Security benefits in November 1994.
