When dispatched to the residence, BIA police discovered Keisha Colorow in a bedroom with a stab wound to the chest and leg and a bloody knife lying nearby. She was transported to Southwest Memorial Hospital and pronounced dead.

A witness stated he “saw Jaycene standing over Keisha with a knife in her hands,” then she left the residence when police arrived, according to the affidavit.

Jaycene Colorow returned to the residence about 3 a.m., the police report said, and was arrested for intoxication and jailed.

On Feb. 12, she was charged with first-degree murder in Indian Country and is in federal custody, according to the U.S. Attorney’s office. The penalty for the 1st degree charge, if convicted, is life in federal prison, and or a fine of up to $250,000.
