Past Family Sa, Worried About Abuser Access To Children

Location: California

Hi everyone,

Hoping to get some clarity on what (if any) options I have regarding what I'm about to share.

My wife (we'll call her Karla) and her sister ("Jo"), now both in their late 40s/early 50s, were victims of repeated sexual assault and abuse by their father ("Bob") growing up. Their mother ("Debbie") was physically abusive but not sexually, or so we thought until recently.

As such, Karla and I have been no contact with Bob and Debbie for many years. Jo and her family have maintained a relationship, as Jo has never really "dealt with" her abuse and remains sort of in denial about it all.

Recently, Jo's now-late 20s son "Andy" came to his aunt and I and shared that he too had been a victim of many incidents of sexual assault, at the hands of both Bob and Debbie, each solo and together, over the span of about a decade, concluding about 15 years ago.

Unlike his mom and aunt, he has vivid memories of the assaults, when and where they took place, who was involved, etc. What Andy shared triggered some memories for Karla, and it's clear Debbie was involved in her daughters' SA events too.

He told his parents, and while Jo still drags her feet on confronting Bob and Debbie (which is infuriating), nobody is interested in pressing charges right now (Bob is still considered by most - not me - as the primary "problem" and he's in the final months of terminal cancer).

I consider Debbie an enormous problem, as she is recently retired from a career in early child education. I expect that once Bob is gone, and if Jo & family cut her off financially, she'll go back to work and have access to kids.

I may be alone in our family in pursuing this, and may have to do it anonymously - but what are my options here? I'm sickened by even the slightest prospect that she might be able to hurt more kids. Any feedback or help is appreciated, and I'll check back in to answer any follow up questions.
