It's hard to believe that it's been more than seven years since America watched with bated breath as the jury made a decision about Casey Anthony's highly-publicized murder trial. For those unfamiliar with the case, she was accused of killing her then two-year-old daughter Caylee, who was reported missing in July 2008 by her maternal grandmother, Cindy Anthony. After Cindy had gone more than 31 days without seeing the toddler, she alleged that Casey's car smelled like a dead body.

Of course, since the trial in 2011, many people still have a lot of questions about Casey's trial and Caylee's death — including not only why Casey Anthony got off, but how? With The Case of Caylee Anthony airing on Oxygen on May 19, check out some of the most common questions people have about the case below to get ahead of the special.

Who was Caylee's father?

There has never been an official answer to who fathered the late child; there have been many suspects when it comes to Caylee's paternity, including Casey's ex Jesse Grund. During the trial, Casey's lawyer implied that Casey's brother may have impregnated her. Cindy — Casey's mother — has stated that the man who fathered Caylee died before the family made headlines, but to this day, her paternity remains a mystery.

Was Caylee ever found?

Sadly, in December 2011, Caylee's remains were found alongside a blanket in a garbage bag in a wooded area near Anthony's home. At the time, duct tape was also discovered, but there are still debates about whether or not it was found near the skull, or near the mouth of the child.

What was Caylee's cause of death?

Though Caylee's death was ruled a homicide — because of the presence of the duct tape — the official cause of death on the child's autopsy was listed as "death by undetermined means" by the medical examiner. When Caylee's body was found, it was only skeletal remains — making it harder to determine a potential cause of death.

Does Casey talk to her parents?

Casey has been estranged from her parents since the trial, which is understandable — considering, at one point during the trial, Casey claimed that her father sexually abused her as a child. When Casey broke her silence in March for an interview with the Associated Press, Casey's parents said they were "hurt" by it. They released a joint statement, "After years of silence, Casey Anthony has decided to complete an interview and has once again pointed to George Anthony, her father, as a suspect in the disappearance and death of his granddaughter, Caylee."

How did Casey Anthony get off?

In October 2008, Casey was charged with first-degree murder, just months before her daughter's skeletal remains were found in a trash bag. One question that people still ask about this trial, though, is how did Casey Anthony get off? For those who may not remember, Casey was acquitted after being found not guilty of first-degree murder, aggravated manslaughter, and aggravated child abuse — while she was found guilty on four counts of providing false information to law enforcement.

One juror, Jennifer Ford, told ABC News at the time, "I did not say she was innocent. I just said there was not enough evidence. If you cannot prove what the crime was, you cannot determine what the punishment should be."

Where is Casey now?

Today, Casey Anthony lives in South Florida with Patrick McKenna, a private investigator who worked on her defense team. Though she is said to be an aspiring photographer, she also assists Patrick with his work by lending a hand when it comes to research for other cases.
