The two overarching unanswered questions in the missing baby Lisa Irwin case are "Where is Lisa?" and "What happened to her on the night of Oct. 3 to Oct. 4?" But there are many other unanswered questions that add to the mystery surrounding the little girl's disappearance.
The answers to some questions not addressed publicly may be known to investigators. Some of the answers may not prove relevant to where baby Lisa is and what happened to her. But as the media scrutiny continues, what is not reported often seems as important as what is.
Here are a few of the many unanswered questions in the investigation into the reported disappearance of Lisa Irwin:
* What kind of repairs was Jeremy Irwin making at Starbucks that kept him out six hours later than he expected? Irwin said he expected to be home by 10 p.m. Oct. 3. Yet, the electrical repairs he was making at Starbucks allegedly kept him late, and he didn't return home until about 4 a.m.
* What became of the baby wipes and baby food Deborah Bradley was shown buying in Festival Foods surveillance video Oct. 3? Were any of them opened and in use in the Bradley home by the time police arrived to investigate baby Lisa's reported disappearance?
* Is Bradley a member of a frequent shoppers club that tracks purchases, and if so, do the records suggest that the timing of her purchase of baby wipes and baby food was consistent with her normal purchase intervals?
* How much wine was missing from the wine box Bradley was drinking from the night baby Lisa disappeared? Does the amount of wine missing, combined with evidence of what and how much neighbor Samantha Brando was drinking, support Bradley's claim of blackout drunkenness that emerged more than 10 days into the investigation?
* Did Bradley appear drunk or hung over to police when they arrived at her home at 4 a.m. Oct. 4?
* Do phone records show an attempted call from Irwin to Bradley during the hours he was at Starbucks? Irwin initially said he did not try to call Bradley. After one of his lawyers claimed to have viewed phone records, the lawyer announced without explaining the change in story that Irwin did try to place a call to her. This was allegedly how Irwin learned the family's cell phone service had been shut off for nonpayment.
As the investigation continues and new details eke out, the unanswered questions pile up.
