Fifth victim of serial killer who hid his crimes in plain sight is identified 40yrs on after he tortured & slayed women

Margaret said a cold case detective reached out to her in July 2021 and told her they were looking for someone who "may have lost a sister" in 1980 in Tampa or Hernando Country area.

Officers visited Margaret in Cape Coral to establish a timeline and collect a DNA sample, to help provide closure. The DNA sample came back positive.

"He said that is the first cold case that he's ever had that's gone that far: to be able to completely deliver the remains to the family," John explained.

Teresa's remains are currently at the Hernando County medical examiner's office and are expected to be delivered to the family at a designated funeral home.

"The sad part of it is my whole family never knew what happened to her. My dad dies without knowing, my mom died without knowing... my sister died without knowing."

Mansfield killed four Florida women and girls and a Californian woman between 1975 and 1980, and buried the bodies of four victims at the Spring Hill home family home.

Three of his victims have been identified as mother-of-three Rene Abbey Saling, 29; Sandra Jean Graham, 21, and Elaine Louise Ziegler, 15.

Mansfield's murders came into sight after the body of Saling was found near a campsite where the Mansfield brothers were staying in California.

The discovery prompted a search of the junkyard surrounding the family's mobile home in Weeki Wachee Acres area of Spring Hill.

The skeletons of Graham and Ziegler's were discovered at the home, as well as a partial skeleton.

Two other women, whose remains were found at the property where Gary and their father William Mansfield Sr. still live, remain unidentified.
