ADA, Okla. -- A 25-year-old man is now charged with first degree murder in the death of an Ada woman. Keith Allen Gastineau reportedly killed 26-year-old Crystal Jade Cavanaugh on Saturday night at his Ada apartment.
She had reportedly asked for his help after having had a fight with her boyfriend.
We're told Gastineau let the woman into his apartment when she said she needed a place to go.
Assistant District Attorney Chris Ross says Gastineau loaded a .45-caliber pistol in case her boyfriend came into his apartment but decided he felt threatened and shot Cavanaugh instead.
The Oklahoma Bureau of Investigation is currently looking into the case.
