Deputies have arrested a 70-year-old woman in connection with a cold case homicide in Twin Peaks, California, where a man was fatally shot in 1993, authorities said Thursday.

On Feb. 27, 1993, San Bernardino County sheriff's deputies were called to a home in Twin Peaks, an unincorporated area 75 miles east of Los Angeles, following a shooting.

The victim, 35-year-old Rick Hafty, was pronounced dead at the hospital.

“At the time, investigators exhausted all leads and the case remained open,” the sheriff's office said in a statement Thursday.

Detectives re-opened the case in June, with interviews and another examination of the case's physical evidence. Investigators took Diane Cook, 70, into custody on Wednesday.

Cook is in jail on $1 million bail. It was not immediately clear whether she had an attorney who could speak on her behalf.
