A spokesman for the family of a man suspected of kidnapping a 16-year-old Southern California girl and killing her mother and brother wants DNA samples to determine if the suspect fathered the children.

Andrew Spanswick told KGTV-TV in San Diego that there are rumors that James Lee DiMaggio fathered both children and that it's odd that the suspect named their maternal grandmother as a life insurance beneficiary. A spokeswoman for Hannah Anderson's family disputes the suggestion, saying DiMaggio didn't meet Hannah's mother until she was six months pregnant with her.

Anderson family spokeswoman Stacy Hess also says Brett Anderson's DNA was used to confirm the identity of 8-year-old Ethan Anderson, whose remains were found Aug. 4.

The DiMaggio family spokesman didn't immediately respond to messages from The Associated Press.
