Just unbelievable

Don't know all the ins-and-outs legally, but I should think if someone has died, there would be some form of inquest, in which case the bike would form part of the evidence - thus if someone has taken it (or tampered with it), then it could be argued that the theft/tampering has hampered / obstructed any investigation (so potentially leading to prosecution on that account, as well as a theft charge).
