Listen to ‘Internal Affairs’

Dateline NBC’s latest series, “Internal Affairs,” reports on an obsessive love affair that turned deadly. Host Josh Mankiewicz brings listeners to Greeley, Colorado and shares what happened one freezing night during a terrorizing encounter and the search for a costumed killer. This podcast chronicles poor choices, the attraction between people who lived lies at home, and what happened when their law enforcement had to investigate some of their own.

Wife and mother Heather Garraus was married to Ignacio Garraus, a Greeley, Colorado police officer. When Heather was killed in 2007, investigators suspected the murderer was someone she knew.

Investigators identified Shawna Nelson as a suspect, the wife of a former Weld County investigator, who was arrested and stood trial for killing Heather. Shawna was having an affair with Heather’s husband, Ignacio. They were colleagues at the Greeley Police Department. On the podcast, hear how Heather was portrayed as a woman who would do anything to get what she wanted.

Stream “Internal Affairs” from the first episode to learn about all parties, the love triangle, and hear interviews with witnesses and those involved in the case. The series details how investigators named Shawna as a suspect and who else wound up pleading guilty in the case. Shawna was found guilty of first degree murder and received a life sentence in 2008 without any possibility of parole.

Ken Nelson, Shawna’s husband and Weld County, Colorado sheriff’s deputy, was also charged for the crime. He was accused of tampering with evidence and allegedly handled the gun used to shoot Heather outside her workplace, Greeley Credit Union. Ken initially said he was intent on divorcing his wife after he realized she was cheating and pregnant with Ignacio’s son. But he later said they agreed to stay together and raise the child. The podcast chronicles the relationships of everyone involved, the drama leading to the crime, and more.

This series is filled with twists, turns, revelations, and the results of questionable decisions. We recommend “Internal Affairs” for fans of “The Seduction,” “Snapped: Women Who Murder,” and “Dateline NBC.”
