'Dateline' investigates case of Sarah Jean Hartsfield, former Minnesotan accused of killing husband

ALEXANDRIA, Minn. — A murder case involving a former Minnesota resident will be examined by NBC's "Dateline" Friday night, April 28, at 8 p.m.

Correspondent Keith Morrison will conduct a cross-country investigation to unravel the case of Sarah Jean Hartsfield , a former Douglas County resident.

"When a woman's fifth husband dies in a hospital under suspicious circumstances, an investigation reveals a checkered past full of spurned lovers and wild allegations," said Dateline in a description of a video sneak peak of Friday's episode.

Hartsfield stands accused in Texas of killing her husband and is alleged to have told one of her ex-husband he wasn't allowed to come home unless he killed the wife of another ex-husband.

"We heard so many strange and conflicting stories, for a while we didn't know what to believe," said Morrison, in a voiceover of a teaser video for the episode. "We decided to conduct our own investigation into Sarah Jean. What was true, and what was not? Finding out would be a long, strange trip indeed."
