I think the video you linked to might have been superceded by the tribute video from Sian's father so I haven't been able to listen to it.
Apologies if I'm missing something but I don't understand why it seems this case is moving faster than VTs
VT was arrested on Thu 20th Jan, charged Sun 23rd Jan, appeared before magistrates on Mon 24th Jan, bail hearing was Tues 25th Jan with the Prelimanary Hearing on Mon 31st Jan. That's a total of 11 days from arrest to Preliminary Hearing.
CH was arrested on Thu 24th March with a Preliminary Hearing set for 8th April. That's 15 days from arrest to Preliminary Hearing.
I don't know about anyone else but it seems like donkeys years from we've heard anything about VT.
