I too had the same thought........a religious older man would probably wear a gold cross on a gold chain...
These type of crosses are popular with younger hippier, bohemian types and worn with a black leather flat string.....I actually have a wooden cross like this that had one of the flat leather shoelace ties. They are probably more popular with girls, so maybe he took it from a girlfriends, sisters collection or similar.
My thinking at this stage, is that this guy has had urges for a while hence the attempted abductions. I think he has put this near the body parts...ugh, maybe because he finally acted on those urges and then had tremendous guilt.
Like Nursebeme and a few others have said, the police are then trying to see if this is linked to the abductions in Kender.
However my only problem with that is werent they adult women??? for those who have been on here a while and seen serials, have you seen someone go from wanting to rape women to crossing over to little girls??
Maybe he has had those urges and saw her, a female, walking by herself and it was too much to resist and too easy......could also be the reason for the cross, absolute guilt over killing a little girl...
just a couple of thoughts.
