After a manhunt coordinated by the San Bernardino Police Department, an 18-year-old female was taken into custody for allegedly stabbing her 21-year-old boyfriend to death.

Hemet police arrested Nakasia James after a Facebook account reportedly belonging to her posted a confession for the fatal stabbing of Dorian Powell. According to KTLA, the post described a domestic dispute in which an inebriated Powell supposedly struck her in the face before she grew angry and killed him.

Powell’s body was found early Monday morning after police received a call from a person claiming they’d been stabbed by their girlfriend. He was pronounced dead at the scene.

This is an ongoing investigation.
