I found a study of burglars several days ago (see attached .pdf), with some interesting info regarding sexual predator burglars....it makes me very concerned that this monster's violence could escalate:
sexual offenses including rape convictions and were labeled sexual preda-
tor burglars. Classes 3 and 4, the drug-oriented and sexual predator
burglars had significantly more burglar offenses (M= 8.7 and 8.5,
respectively) than subgroups 1 and 2. Given that the sample com-
prised of career offenders, all subgroups displayed offense versatil-
ity, yet as described above, there was also evidence of
specialization particularly with respect to drug crimes and sexual
offending
.....................
The final subgroup, sexual predator burglars, was clearly
involved in high levels of sexual deviant acts such as rape and
prostitution⁄ solicitation offenses. There is also evidence that sexual
predator burglars were the most violent. This subgroup possessed
numerous aggravated assault and robbery charges. They also had
the longest criminal careersspanning over 30 yearsand the ear-
liest age of offense onset. Perhaps, the burglaries committed by this
subgroup are at least partly motivated by sexual compulsions and
thrills associated with entering the dwelling of a victim. Many bur-
glaries may have been motivated by a strong desire for rape of a
target that they had been stalking. This final subgroup may be the
most dangerous of all with a high level of criminal persistence,
intensity, and interpersonal violence. Two additional points are
noteworthy about the sexual predator burglars. First, Class 4 com-
prised 6.1% of all offenders but was disproportionately involved in
the most serious forms and total incidence of crime. Empirically,
the 6.1% prevalence estimate is similar to the 5% threshold used to
define career criminality (18,29,30). Second, recent analyses of a
sample of 654 murderers found that offenders with prior arrests
and convictions for rape and current involvement in burglary were
significantly more likely to commit multiple homicides (31).
