Federal agents allege a Chicago couple posing as Kenyan refugees whose lives were in danger scammed more than $800,000 from an order of Carmelite nuns in Wisconsin, the Chicago Tribune reported Thursday.

An FBI affidavit filed in Milwaukee also alleges that Angela Purity Martin-Mulu, 35, and Edward Bosire, 39, took almost $20,000 from a Carmelite monastery in Des Plaines, the newspaper reported.

According to the Tribune, the couple posed as brother and sister and took meals, gasoline, cash and aid from the nuns.

"You feel like you've been stepped on," Mother Marie Andre, superior at the Carmelite monastery in Des Plaines, told the Tribune.

She said the couple would sit in her office sobbing about insurance problems, auto repairs and money problems. They told her their father was a high-ranking official who was in danger, so they fled to the U.S. illegally.

The couple, in the U.S. legally, according to the FBI, took money from the Carmelite monastery to pay for medical treatments, but there was no record of either receiving care at the Wisconsin hospital where they claimed to be treated, the Tribune reported.

They are being held on a mail fraud charge in Chicago and are due in court Friday.
