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?
Heheh. Not at all.
I read it as saying that it was Norberto who suffered from the fractured skull because the mother's boyfriend paid Norberto a visit before the police took control.
