-no body:
That won't be a problem with the jury if they can prove there was a murder, and explain where the body is.
There is speculation that the body was put in an incinerator. If that is true, then the fact there is no body will not be a problem at trial.
- a consumptive DNA test:
I don't see why that is considered a problem. That happens quite often, when a crime scene was cleaned, but tiny fragments of forensic evidence is found in cracks and crevices.
That is a good thing, not a bad thing, imo. If it is brain matter, it may negate the need to show a dead body to prove there was a murder, for example.
- two competing theories of murder:
They are not really 'competing.' They are very similar, in that it involves the same killer and same victim, involved in the same killing, in the same place and same time.
- had to enter KB townhome 3 separate times:
And? How many times would one expect the detectives and forensics teams to visit the crime scene? I'd expect at least 3, if not more.
As they investigate and interview witnesses, more questions and ideas emerge. That's a natural process.
- delaying tactics, eg, won't unseal probable cause AW:
I don't think it is all that unusual, in cases where others may be involved as accomplices or involved witnesses.
