WASHINGTON – More than 89,000 stimulus payments of $250 each went to people who were either dead or in prison, a government investigator says in a new report.

The payments, which were part of last year’s massive economic recovery package, were meant to increase consumer spending to help stimulate the economy.

But about $18 million went to nearly 72,000 people who were dead, according to the report by the Social Security Administration’s inspector general. The report estimates that a little more than half of those payments were returned.

An additional $4.3 million went to more than 17,000 prison inmates, the report said. Most of the inmates, it turns out, were eligible to get the payments because they were newly incarcerated and had been receiving Social Security before they were locked up.

The report was dated Sept. 24 but was just recently posted to the agency’s website.
