LEBANON, Ohio - Convicted murderer Ryan Widmer recently fathered a baby boy.
That will be part of a national television program featuring Widmer's case airing Friday.
"Dateline NBC" is scheduled to air a two-hour episode about the Widmer case, in which the child and the child's mother appear.
During a clip previewing the show, Dateline reports that Widmer, 30, fathered a child with a woman he met after the first Dateline NBC story aired in September 2009. According to the clip, that child was born in the summer after trial number two. That trial ended in June 2010.
The mother of the child says in the clip, "There's no way that he could have done this, ever."
The woman interviewed moved to the area last year to be with Widmer. She did not attend the third trial, but was present when the final verdict was read.
Friday's episode is called "The Bathtub Mystery" and is scheduled to run from 9 p.m.- 11 p.m.
Dateline also previews an interview with Ryan's mother, Jill, as well as the lead detective in the case, Jeff Braley of Hamilton Township police.
Ryan Widmer was convicted in a third trial of drowning his wife, Sarah, in their Hamilton Township home in August 2008. Widmer is appealing the conviction.
The first trial was ruled a mistrial and the second trial ended in a hung jury.
