Collecting swimsuits could be considered an unusual and interesting hobby or it could fall within the definition of sexual deviancy depending on the circumstances in which the items were acquired.The important point is evidence of what.
Collecting swims suits is not a crime. Perhaps owning starter pistols isn’t either.
CSA images are a crime but what is most puzzling is that he hasn’t been charged for this offence despite many reports of 8,000 images… something is amiss.
This is evidence that CB has a sexual interest in children. But that is already established, his criminal record proves this.
This information may convince you but it a very low threshold. As we saw in the rape trials, the fact that he had visited HaB’s apartment block, and that the profiler said he was extremely dangerous did help secure a conviction.
Circumstantial evidence requires inference. What we can infer from all the information that has been leaked is that CB is a sexual criminal - hardly a revelation.
What this evidence does not infer is that CB committed a crime against MM.
For example had the owner collected them legitimately or was it an indication of a fetish driven by the illegal and criminal action of acquisition from a drying area or a burglary.
Interestingly CB’s criminal conviction for the aggravated rape of DM recalls to mind the opinion of the expert opinion voiced at CB’s trial which outlined the level of his dangerousness in no uncertain terms.

An Examination of the Home-Intruder Sex Offender
AbstractOne particular crime location in sexual assaults is the victim's residence.
Similar to sexual burglars, "home-intruder" sex offenders choose to assault the victim in her residence, most likely in their bedroom.
The aim of the current study is to analyse modus operandi, temporal factors, and victim characteristics in a sample of 347 stranger sexual assaults committed by 69 serial sex offenders to determine which factors may be more relevant to sexual assaults committed in the victim's residence compared with sexual assaults committed at another type of location. Our hypothesis is that offenders who choose to sexually assault victims in their home constitute a specific type of sex offender, one that resembles the sexual burglar. Results showed that modus operandi (e.g., burglary), temporal factors (e.g., time at crime scene with victim), and victim characteristics (e.g., age, victim-offender relationship) were significant in predicting whether the victim encounter, crime site, and victim release site were located at the victim's residence or not. Moreover, these findings were generally significant across the three crime locations, which can be explained by the high consistency in location during home-intrusion sexual assaults. Situational crime prevention strategies aimed at making a residence less attractive for offenders should help reducing this particular type of sexual assault.

None of that bears any reference to the circumstantial evidence in the MM case; nor does it lend inference to her case.
That evidence painfully collected and collated over the years by many different investigations and investigators including those presently tasked with working the case, will be the stand alone evidence unique to the circumstances of the case which kicked off in 2007. And which will decide whether or not CB will be indicted and brought to trial.
