JOLIET, Ill. (CBS) – A Will County attorney is looking to write a book about his role as foreman on the Christopher Vaughn murder trial.

As WBBM Newsradio’s Lisa Fielding reports, Dan Lachat says everywhere he goes, he’s asked about the case.

“Everyone I know says I should write a book,” Lachat says.

Now, he says, it’s an experience he wants to share.

“I know there is a lot of interest in it locally. That’s why I thought about the idea of a book,” he says.

Over the course of five weeks, he and his fellow jurors heard from 100 witnesses and had to go through 700 pieces of evidence, but it took them less than an hour to find Vaughn guilty of killing his wife and three children.

“Everything that we saw and heard really pointed to Christopher Vaughn,” he said.

Lachat says there was no doubt in the jurors’ minds of Vaughn’s guilt, and they never even considered the defense argument that his wife committed the murders. He also said jurors were struck by Vaughn’s lack of emotion during often gruesome testimony.

Prosecutors said Vaughn shot his family to death in their SUV in 2007, in a bid to start a new life in the Canadian wilderness.

Lachat says the trial has affected him for the rest of his life.

“The impact that this has had, it has changed my life seeing the things that we did. I also have more respect for the law enforcement personnel as far as the work they did on this,” he says. “All I can say is love your family. It’s made me love my family more because of it.”

Vaughn faces life in prison and will be sentenced Nov. 26th.

Lachat says he’s in the preliminary stages of writing the book’s first chapter.
