A Columbia City man already being held on homicide charges related to his father's death led investigators to what is believed to be the remains of his 91-year-old mother, Frieda Bahl.
The body a woman believed to be Frieda Mae Bahl was found buried in a wooded area off Smith Road, after Stephen Bahl, 59, of Columbia City, told investigators where to find her remains.
The body has been transported to the office of the Oregon Medical Examiner for an autopsy to confirm the identity and determine cause of death.
The body was found not far from Frieda Bahl's home at 700 James Street.
Frieda Bahl was reported missing in May, but Columbia City Police Chief Mike McGlothlin said investigators could only narrow the time of her disappearance to sometime between July 4, 2010 and May 16, 2012.
Stephen Bahl was arrested on Aug. 7 and was charged with multiple counts of criminally negligent homicide, hindering prosecution and theft in connection with the death of Bahl's father, James Bahl, who died in 2009.
Bahl pleaded not guilty to those charges on Aug. 13
He is currently being held on $210,000 bail and is awaiting additional charges.
