I googled and found in Wikipedia that he was born in Auburn, New York (whereever Auburn NY is...).
I think Walsh's son was kidnapped in Florida. It's really sad because the mother was a couple of isles over looking at a lamp, and the boy was in the toy department with some other kids. A security guard came over and made the little boys leave the store! Why she didn't take to them to an office and call for parents is beyond me. Anyhow, the Walsh boy was made to go outside, and this killer was driving by and saw the opportunity.
