Where did you read this?
It's also stated in the HLN documentary. I never watch that network, but it was mentioned in the previous thread a month ago.
It aired in March, but I found it on Comcast's OnDemand.
It's going to be interesting now that he is the known killer. He chose all of his victims for specific reasons and those reasons will become clear now.
One woman lived at an apartment complex that his SIL lived. She didn't do her laundry at the complex, but instead took it to her parents house. He followed up on the pattern and raped her at the parents house.
He stopped the attacks in 1981 within few months of his first born child. There is a break of five years and then his last attack occurred within a few months of his second born in 1986. He had three children with his ex-wife/estranged wife who is a family law attorney. His daughters became a physician, a PhD, and the youngest born in 1989 is in grad school.
