"She opened her door and said, 'look at all this stuff people have given me,'" said another person.
McCall allegedly conned friends and Good Samaritans out of thousands.
Lt. Dan Mahla with the Clay County Sheriff's Office says she even ran her scam at her son's schools.
"One of the local high schools here in Clay County, she did approach them and started the same scheme that she had done at a middle school here in Clay County in the past."
They say teachers opened their checkbooks and convinced others to do the same. In an e-mail obtained by Action News, the principal of one of those schools thanked Good Samaritans for coming forward with cash for McCall.
"People really want to pour their hearts out and they want to give to those less fortunate."
By the time that email was sent in late 2011, some people were having their doubts. McCall had claimed to be dying for more than a year. But, many wanted to know why she still looked so healthy?
People had questions for Mary Ann McCall and so did Clay County detectives. They investigated her for months. On Friday, they brought her in for questioning. That's when, deputies said, Mary Ann McCall did the most surprising thing of all.
"She did confess to the alleged crimes in this case."
Sources in the Clay County Sheriff's Office say Mary Ann took nearly $100,000 from people. Investigators expect to uncover even more victims and more money in the coming weeks.
Mary Ann McCall is facing charges of felony grand theft and felony fraud. She's currently being held on $250,000 bond.
