WAKE FOREST — A Wake Forest woman who stabbed her boyfriend to death in 2013 pleaded guilty Tuesday to involuntary manslaughter.
Krystal Terin Delgado, 28, was sentenced in Wake County Superior Court as part of a plea arrangement she made with prosecutors for her role in the death of Dorian Kwame Cunningham.
She will be in prison for at least 16 months.
Cunningham died from a single stab wound received on March 6, 2013.
Investigators initially ruled the death accidental after Delgado told law enforcement officers that her boyfriend had tripped over a pile of clothes and impaled himself with a knife.
But the story changed, and she subsequently was charged with first-degree murder.
Delgado then told law enforcement officers that her boyfriend had abused her often during the past year and that the stabbing occurred as she fought him off in self defense.
The couple had been drinking that night, according to prosecutors. An argument ensued and Cunningham began pushing, hitting and choking Delgado.
Delgado, according to prosecutors, stabbed Cunningham once in the chest, a fatal wound complicated by the large amount of alcohol he had consumed.
