But authorities have now called the tipster's motives into question. On Monday, prosecutor William McCauley said in a filing that the tipster was a woman in a "sexually explicit relationship" with Hernandez.  Although McCauley did not give details of the alleged relationship, he said that the woman – identified only as "Katy" – had sent him sexual letters.  McCauley said that the tipster concocted the story because she believes that Hernandez is innocent and hopes to continue her relationship after he is set free. He classified the tips as an "unwarranted fishing expedition."  Even if the tipster could prove juror misconduct, Hernandez would not walk free.
