PONTIAC - Camera crews and producers were at the Livingston County Courthouse this week, gathering material for a Court TV documentary about convicted murderer Mark Winger.

Winger, 44, was convicted in 2002 of killing his wife, Donnah, and airport shuttle service driver Roger Harrington in 1995.

Winger had claimed he shot Harrington after catching him fatally beating Donnah Winger at the couple's Springfield home.

Police originally believed the story. New information came to light, however, and Winger was arrested in 1999, convicted in 2002 and sentenced to life in prison.

Winger saw another 35 years added to his sentence Monday after he was convicted of soliciting the murders of DeAnn Anderson, a key witness who testified against him, and Jeffrey Gelman, a real estate developer and former friend.

Winger was convicted of asking fellow Pontiac Correctional Center inmate Terry Hubell, who is serving a life sentence for the 1983 murder of a 14-year-old girl, to find a way to kill them. Winger later was moved to Tamms Correctional Center.

The documentary will be aired on a Court TV series called "Murder by the Book," where well-known American crime novelists narrate and offer insights into the real-life crime. Each one-hour episode also will feature interviews about the crime.

The episode on Winger's case will be hosted by author Harlan Coben, said Fred Peabody, a freelance producer from Los Angeles in Pontiac for the filming. Coben's bestselling books include "Tell No One," "Gone for Good" and "Darkest Fear."

Peabody said Winger's case seemed perfect for the series because there seemed to be a series of unusual events that happened in the case. Those included the case being reopened, new witnesses coming forward and the subsequent attempt from inside prison to have people killed.

"It's an unusual series of crimes that you don't often come across," Peabody said. "It has those twists that you would find in a good nonfiction story - in fact you would find them in a good fiction story."

Peabody said Thursday was the crew's first day of shooting in Illinois. The filmmakers interviewed First Assistant State's Attorney Carey Luckman that day.

They crew also planned to film in Springfield and Chicago.

Producers said the episode may be shown Dec. 17.
