Re the walk version...
Text copied from bail hearing doc...
The defendant initially told police and other witnesses that it was usual for the deceased to take a morning walk on week days and that he was concerned that morning because the deceased was due to attend a work seminar and had planned to leave the house at 7am. The defendant told his sister Olivia Walton of the deccased's walking route at about 6.30am on 20 April 2012. The defendant told another witness, Elise Nielsen, a long term friend of the deceased, that the deceased normally went for a walk at about 10pm in the evening. The defendant identified two possible walking route to uniform police, however, three hours later told the deceased's parents that he did not know the walking route. That is, within a few hours the defendant provided four differing accounts about the walking routines undertaken by the deceased. Enquiries with the deceased's parents and close friends indicated that the deceased was not known to walk for excercise and was unlikely to have gone walking late at night. Extensive enquiries were conducted along the suggested walking routes with no persons coming forward having witnessed anyone matching the deceased's description walking at either of these times in this area.
