Russell Wasendorf Sr., the Midwest Madoff who admitted cheating his brokerage customers for 20 years, appears to be in no rush to get out of jail.

The disgraced founder of Peregrine Financial Group, out of the blue yesterday, canceled his bail hearing scheduled for today — without setting a new date.

The 64-year-old businessman has been held in a Cedar Rapids, Iowa, jail cell since early July after an unsuccessful suicide attempt in the wake of his startling confession.

The judge yesterday granted his request.

Wasendorf’s confession came in a suicide note to his wife, whom he married just the week before.

In the note, Wasendorf admitted that he fooled regulators by forging bank documents and that he carried out the scheme alone.

But regulators have said they are suspicious about Wasendorf’s lone-wolf claims.

Daniel Roth, president of Peregrine’s front-line regulators, the National Futures Association, told CNBC yesterday that he is skeptical that Wasendorf could have physically carried out the crime by himself given the “sheer volume of forged documents that were produced as part of this scheme.”

Roth called the number of documents produced to fool regulators “staggering” and said they give “legitimate cause for question as to whether more than one person was involved.”

Peregrine has filed for bankruptcy and regulators have sued both the firm and Wasendorf, alleging he stole more than $200 million in customer funds.

Meanwhile, Wasendorf’s son, Russell Wasendorf Jr., put his posh five-bedroom home in Cedar Falls up for sale earlier this week for $550,000, real-estate records show.

The son, a top executive at Peregrine, bought the house, which boasts a whirlpool and outdoor kitchen, for $505,000 in 2010. Wasendorf Jr.’s Chicago lawyer, Nicholas Iavarone, didn’t return a request for comment.

However, he told CNBC that the move is because Wasendorf Sr. is “public enemy No. 1 here, and he [Wasendorf Jr.] doesn’t want to stick around.”
