How Kristin Chenoweth is connected to the Girl Scout murder

Kristin Chenoweth believes getting sick may have saved her life when she was a child.

In the trailer for the docuseries "Keeper of the Ashes: The Oklahoma Girl Scout Murders,"

the Tony-winning actress has revealed that she was scheduled to be on a camping trip during which three of her Girl Scout friends were sexually assaulted and murdered in 1977.

"This is a story I wish I never had to tell," Chenoweth says in the trailer. "It haunts me every day."

Chenoweth returned to her home state to participate in reexamining the murders of Lori Lee Farmer,

8, Michele Heather Guse, 9, and Doris Denise Milner, 10, at Camp Scott near Locust Grove, Oklahoma.

In the trailer, the actress explains how much she loved going to camp as a Girl Scout and how she saw the troop members as her "sisters."

"I never once thought anything bad could happen," she says. "But I came to learn what murder was."
