It also says they went to the Movies Monday, Monday was the 10th. They went to the Movies on the 11th, Tuesday. Then Zuzu missed her exam and job the next day, Wednesday the 12th
I asked a friend who was with her on Monday for clarification. Her exam was a makeup test on Wednesday. Not everyone's midterm.
The movie theater is free for students on Monday, she did go that night with the person I spoke with and the group of friends (who have all been extensively questioned and cleared). That night she and RF left the group to go to the other screen at the theater. Rumors and reports are that they were arguing. One of the friends in the group was a male she referred to as her best friend and was getting closer to dating. She was at the coffee shop with this friend on Tuesday before the movie. If she went with the best friend on Tuesday and then met up with RF after, that would fuel the arguing at his apartment.
I wish the LE and media were more clear on these details.
