Damon (Peter) is reportedly interested in surfing and bicycle riding among his other hobbies...
DNA testimony was given by a femal forensic specialist/biologist but I don't recall her name.
Costello (bought their house in 1993) said the van Dams told her they were selling the house because they were moving to Texas. News reports say the couple moved to San Diego a few years ago.
Thanks for the link! That confirms what I had read before that they lived in FL and then Texas before moving to SD.
