But telephone records, projected onto a white screen for the jury, showed that during the time frame that Constand had claimed to have been unconscious and assaulted she made a slew of calls - late into the night, including calls placed to Cosby.
Directing the jury to the phone records, Agrusa stated: 'On March 16 at 6.30 in the morning you put a call to your friend Sherry (Williams) at 6.30 correct? And then at 6.58 that's a call you placed to Mr Cosby and then you tried him again at 7 a.m.
'And at some point you go to that Central High Dinner. But if you look at line 291 you call Mr Cosby at 9.45 p.m. and then not even six minutes later you call Sherry Williams that same night.
And then in fact you called Sherry again less than a minute later didn't you? And in fact four minutes later you called Sherry Williams again didn't you and this time you talked to her for about 12 minutes.
'This is the night March 16 that you were drugged and unconscious in Mr Cosby's home at about 9.15, 9.30 and you make a call to Mr Cosby to Sherry to Sherry and that same night at 10.06 p.m. and at 10.13 p.m. and you're on the phone once again at 10.06.'
Her voice rising, Agrusa came to her point: 'At the very time you told police you were drugged and unconscious you were on the phone making multiple phone calls.
'But you were passed out? There was no way you were making those calls.'
Rounding on Constand she said: 'You weren't drugged that night were you? You weren't sexually assaulted on March 16 were you?'
'No ma'am,' Constand replied.
Constand appeared calm and composed, smiling occasionally at the jury, acknowledging members of her camp in the courtroom.
