This is by far a very interesting documentary about larrimah . I’m no forensic expert but could a traveller or tourist traveling down that road hit paddy & his dog at an early 4:00am . And carry both the bodies away on a truck and left the scene . There was a part where the public phone booth was made twice calling attempt but decided to give up the call . That could be that mystery driver that wanted to call & also hit both paddy and dog . Panicking at that situation he or she decided to move the evidences away from the small town .
