Alleged serial mail bomber Cesar Sayoc once owned a home that was foreclosed on by IndyMac, the financial institution which changed its name to OneWest Bank and was formerly owned by Treasury Secretary Steven Mnuchin.

Documents confirmed by Associated Press show that a south Florida home owned by Sayoc went into foreclosure on Jan. 7, 2009, according to Florida property and court records. Overseeing the foreclosure was the California-based IndyMac. The bank itself failed during the recession and was obtained by a group of investors that included Mnuchin and renamed OneWest, eventually becoming the largest bank in Southern California. During his confirmation hearings, facing criticisms of his handling of foreclosures, Mnuchin characterized the bank as a "loan modification machine."

The foreclosure paperwork was signed by Erica Johnson-Seck, a lawyer for OneWest who was a central figure in the controversy over the bank's foreclosures, in which the bank signed off on foreclosure documents without vetting them for accuracy. Johnson-Seck testified she signed off more than 750 legal documents a week.

Sayoc has been charged with five federal crimes relating to mailing a dozen explosive devices to Democratic lawmakers and liberal activists. He faces up to 56 years in federal prison, and may face additional charges, according to Attorney General Jeff Sessions.
