i see it logically,
as we are only at the suspect stage - the evidence isn't strong enough for anything more. atm.
if the evidence was strong enough - in the opinion of the prosecutors/judges - we would be at arrest/charge/trial right now.
equally, no prosecutor will have the luxury to continue to look for the 'full story' and 'every fact' just out of their individual professional standards or curiosity. they may want to in an ideal world. but realistically, and financially, their job is to bring provable cases to trial. isn't it just getting to the shortest line to 'provability''?
and they will always have a pile of other cases to get onto. imo.
separate questions re: delay.
if any suspect is found guilty of murdering MM what will the sentence be - surely no need to wait until suspect's current sentence runs its course?
also, why delay when there are parents that want closure?
