I think that sentence needs to be rewritten for clarity as:
After recovering from a fractured skull and a brain bleed inflicted by the boyfriend of the victims mother (the victim was a little girl).Writing quality has really suffered after the invention of the internet. No one uses editors anymore.
They never identified Jose as the boyfriend of a woman or that he bashed the head of the girl that he molested while babysitting her. At least not in this account. Are you getting your information from a different source?
