The insurance company is most likely not going to bother, the claim has been settled with the owner. For them to pursue any claim against Weaver would mean quite a few people having to admit their own shortcomings and lack of due dilligence in allowing Weaver to get away with it in the first place.
The insurance company must be fully aware that holding Weaver to account is not going to get them anywhere and just cost them money that they have no hope in ever recovering.
