I might be wrong, but didn’t Serino already testify that Tracey denied that the screams were those of his son???
If he hasn’t then he will be recalled this week and state that to the court and Tracey and the prosecutors will have to sit there and take it because they are the ones who left Tracey off the stand in their case and did so for fear that he will get torn apart.
I don’t know if he testified about this or not...but good points.
