(WXYZ) - The Kilpatrick corruption case is about to launch into a whole new chapter of extortion allegations.
The next government witness is man named Karl Kado. He was brought into the courtroom Friday to be shown where's he's going to be sitting next week.
We haven't heard much about the former mayor's father lately with Kado, that's about to change.
Kado is key to the next chapter of the Kilpatrick corruption case.
The former Cobo Hall contractor is expected to tell the jury that he gave at least $360,000 in bribes to former mayor Kwame Kilpatrick, his father Bernard Kilpatrick, and former Kilpatrick aide Derrick Miller.
The Kilpatrick's are on trial, accused of running a criminal enterprise out city hall. Miller accepted a guilty plea and is expected to testify in the case.
According to the indictment, Kado paid off the former mayor and his father in order to keep his lucrative cleaning and electrical contracts at Cobo.
He too accepted a guilty plea on tax evasion, and is currently on probation.
Kado is in his 70's and sources tell the 7 Action News Investigators that he has health issues which may or may not impact his ability to testify.
During opening statements, Kwame Kilpatrick's attorney Jim Thomas suggested to the jury that Kado has dementia.
"The jury has to know that he's an accurate historian of what it is that occurred. And if in fact, he can't remember, or if he says he hasn't remembered in the past, then that's something for the jury to factor into it. We'll just have to see how this comes," said Thomas.
Kado's testimony – which could detail huge cash payments allegedly made to the Kilpatricks – has the potential to be very damaging. But Thomas says for the defense – Kado is no different than any other witness.
"Those jurors are looking at the witnesses and evaluating what it is that they're saying, and the logic of what they're saying and the credibility, and in the end, he's part of a very large package the government is putting a nice little bow on, and saying here, convict. On the other hand, we have a different point of view," said Thomas.
While Kado taking the stand will move the feds away from the water department deals that have dominated the testimony for weeks, you can expect to hear more about sewers and water mains down the road.
Big name contractors like Tony Soave, who used to own Inland Waters, and John Rakolta from Walbridge are still expected to tell the jury about their experiences getting DWSD work with the so-called Kilpatrick Enterprise.
Testimony continues on Monday.
