Many questions remain unanswered in the mysterious case of missing baby Lisa Irwin. The 11-month-old's parents, Deborah Bradley and Jeremy Irwin, continue to maintain that baby Lisa disappeared from their home nearly a month ago. Despite following hundreds of tips, police still have no major suspects or leads in the disappearance of baby Lisa.

Still, the case is far from settled and, rather, is shrouded with endless questions. Bradley and Irwin have been uncooperative and have refused to be interviewed separately by police. They've also denied interviews with local reporters, favoring national networks offering primetime interviews, even though local coverage would be more helpful in locating baby Lisa Irwin. Many wonder if parents, Bradley and Irwin, have told police the whole truth.

It also remains unclear how a modest American family could afford the high-profile New York lawyer Joe Tacopina representing them, as well as the New York private investigator, Bill Stanton, hired to help find 11-month-old Lisa. An unnamed wealthy benefactor claims to be paying for Stanton's fees and has also offered a $100,000 reward for the return of Lisa or the conviction of those involved in her disappearance. Who is this benefactor and why is he helping the family?

Not only are police stumped by what really happened to missing 11-month-old baby Lisa Irwin, but the media and the public have become increasingly confused by the events that have unraveled this month in an effort to find her.
