Honestly I'm not sure how effective contacting family members is going to be at this point, since bonbi is clearly determined to reframe the whole situation as "those nasty incels out to hurt me and my boyfriend".
Building as substantial a body of evidence against him as can be collected and taking it to the authorities to prompt them to make their own investigation is probably ultimately the only thing that can really be done.
