My studies are a hypothetical sample and may not apply to this case, but they are worth noting:
Specifically noting LE's reference of a 'sexual component' in the AG case of which we do not know:
In the U.S., sexual homicides by older male offenders (55+) account for only 0.5% of all sexual homicides.
Most offenders in sexualized or overkill homicides are usually (but not always):
• Male
• Under 55
• Often 25–45
This is because:
• physical strength is required
• sexualized motives skew younger
• impulsive violence decreases with age
• offenders over 65 are statistically rare in violent homicide
Many resources:: Age and sexual recidivism) Statistics about sexual assault | INSPQ
(there is much more on this age theory and the sexualization is only one aspect of this case, so I find it helpful to post in snippets so each aspect can be evaluated on its own. I feel this will be a long journey as I don't want to look up all the old posts sleuths shared LOL. So details may have already been discussed.)
So . . . if the offender was around 55 on December 30, 2010, today in 2026, they would be around 71. Could still be alive.
If the offender was 25–45 in 2010, today in 2026 they would be 41–61 now.
