WAUKESHA COUNTY, Wis. (CBS 58) -- A contractor accused of ripping off customers pleaded guilty on Friday in Waukesha County Court.

David Ward pleaded guilty to a felony charge of theft by contractor.

Last month, CBS 58 Investigates uncovered Ward's extensive criminal past that includes more than a dozen felony convictions in Illinois. That led to prosecutors in Waukesha County revising their plea deal.

After entering his plea, Ward admitted what he did to the judge.

"Took a deposit on a job and didn't complete the word," Ward said.

"There's a claim for $30,000 so was it more than one time you took the money and didn't do work?" the Judge asked.

"Yes, your honor," Ward said.

Ward will be back in court for sentencing on April 30.
