I think the fact that the wife is a Inzerillo means that she is against helping the police especially since they have been trying to lock up her husband for the past decade why would should help them out. I think she and her kids were true to Omerta and said fuck the police we want real justice and we ain’t helping them. I’m sure they knew it was this deranged Comello kid since he supposedly rang the doorbell first and apparently the niece was inside the house too. The wife seems pretty legit she has it in her blood she wanted that kid dead for killing frank not locked up.
