That's quite a subjective interpretation of what he might have been doing.
The way he was dressed is normal for the area.
Apologies, perhaps a mod can snip my comment.

In reference to the youtube link frommer posted:
The guy in the red jacket at 4:02 says a pair of shoes were found, and that being a pair made it quite unusual.
I assume if those shoes had been April's, LE would have said so?
However it prompted me to verify what LE said AJ was wearing at the time of her abduction, but all I could find was this:
"Police said she was wearing her white primary school T- shirt, a purple padded coat with fur collar and black trousers."
But there was no mention in that article regarding the type of shoes or boots she was wearing. I wonder if it was stated elsewhere, though I've been unable to find it.
