What an ignorant awful SOB to do such a thing to an animal, when keeping livestock you always have risks but like you say somethings are just not adding up, I wonder if he has ever done something like this before, or is he new to the area, I never see dog traps here but what we do get in this country is gypsies throwing over food full of antifreeze to dogs and poisoning them. Fortunately it does not happen in this village but im always weary incase and never keep the dogs in the garden while im away from the house, please keep us informed of what the outcome was and maybe your friend might think about a camera maybe it's good for security and also for shit like this. @rhondak my heart breaks.
