"Is there any indication of sexual abuse?"
I've seen a recent photo of him, and his eyes look -for the lack of a better word- dead. He knew how to reach his parents, and did so under an alias, with no effort to go back to them. He also knew, from the website, that they were desperate to find him, so the story about Devlin telling him that his parents no longer wanted him is sketchy, at least from the standpoint of the boy's behavior. Even if it turns out that the boy though he was a willing participant, he's a minor child, and therefore not legally accountable for his behavior; Devlin is. He is very likely to have been severly manipulated psychologically, if not also sexually abused.
I am sure you are correct, and equally sure the kid is filled with shame and self-loathing.
Probably didn't think his parents would want a "fag" back.
Well there was tons of kiddie porn found on Devlin's computer according to a newspaper artlice linked on Drudge
As for sex abuse Why else would he kidnap 2 young boys ......
Devlin was so Brazen he called the cops on his neighbors , no wonder Shawn didn't trust the police .
Devlin probalby made Shawn do some sick gay crap took photos & used that crap to manipulate him more .....
