Wake Forest, N.C. — Police charged a Wake Forest woman Thursday with fatally stabbing her boyfriend in the apartment they shared.

Krystal Terin Delgado, of 876 N. Main St., Apt. 218, faces a first-degree murder charge in the death of Dorian Kwame Cunningham.

She was placed in the Wake County jail without bond and is due in court Friday.

Police say Cunningham, 23, died Wednesday night at WakeMed after being stabbed shortly after 6 p.m. at the Glen Royall Mill Apartments, in the home he shared with Delgado and her daughter.

Neighbors reported hearing arguing at the home Wednesday evening.

Investigators initially ruled the death accidental, but later called it "suspicious."

A 911 caller told authorities that Cunningham's girlfriend said he tripped over a box and fell onto a knife that was sticking out of it. 

A town spokesman said police have responded to the couple's apartment 12 times in the last year for domestic incidents.
