The jury in Casey Anthony murder trial took 10 hours and 40 minutes to decide that the accused did not kill 2-year-old Caylee Anthony three years ago. In a dramatic and controversial conclusion to a legal battle that had the nation riveted, the jury pronounced that Casey Anthony was not guilty of first degree murder, aggravated child abuse and aggravated manslaughter. She was found guilty only in four counts relating to lying about the child's missing.

Crowds of people got into a rage outside the Orange County court house and social media erupted in anger over the seeming miscarriage of justice. The prosecution had presented a mountain of circumstantial evidence against Casey but for the jurors, there was no conclusive physical evidence to prove that Casey was guilty of homicide. In other words, the prosecution failed to nail down the cause of Caylee's death.

According to legal experts, this was a verdict very few people who watched the trial had expected. Legal analyst Dan Abrams told ABC News that the jury focused particularly on very minute points of evidence, as it often happens in high profile cases. In this case there was no physical evidence, no trace of blood and no confession.

Casey Anthony wept in joy in court as she listened to the jury's announcement that she was 'not guilty' in three serious counts. Her lawyers praised the verdict and claimed justice was done.  Attorney Jose Baez said this case proved why capital punishment doesn’t work. He said he is happy that he could save a life.

However, Baez admitted that there were no winners in the case. The mystery over how Caylee, the bubbly little girl with big brown eyes, died.

The devastated prosecution sat in stony silence after spending hundreds of thousands of dollars on the case and wove the story of Casey's guilt with remarkable conviction. It was reported that Prosecutor Jeff Ashton was retiring in the aftermath.

Casey went back to protective custody hours after the verdict was announced. She may or may not get out on bail before Thursday's sentencing, depending on the defense stand.

Meanwhile people expressing their opinion on Twitter showed dismay at the verdict, and some even seethed with anger.

Scott Peterson was convicted based on circumstantial evidence. Seems like it was less than what Casey Anthony had in her hand, tweeted Terry McMillan.

Martha Stewart! lied JAIL 1 year!! Casey Anthony kills a kid... and goes home, said Brian-Bee.

Lohan goes to jail for a necklace and Casey Anthony is free. Makes perfect sense, tweeted chrissiemiller.

While some compared Casey Anthony trial outcome to other high profile cases, some others reserved harsh comments for the young mother who the world thought had killed her beautiful daughter.

Casey Anthony is the most hated woman on earth right now...Actually she's not a woman ...shes a monster. R.I.P Caylee, tweeted Ram Danielle.

It's not fair to compare Casey Anthony to OJ Simpson because OJ's kids are still alive, said Not Gary Busey.

For another Twitter user, the justice system in the country had failed abjectly. The casey anthony is yet another dissapointment in our justice system. May god do his justice since america failed to do so, tweeted Alyssa Morales.

I am heart sick realizing the millions Casey Anthony will make on the blood of her precious lil' daughter,| said teri henson, referring to Casey's post-acquittal life of writing a memoir and making exclusive media appearances.

Everyone is saying if they ever see Casey Anthony they'll kill her, said Bayan Quran.

The jurors refused to speak to the media after they pronounced the acquittal. Legal experts have said a retrial is near impossible in this case as it would be 'double jeopardy.' Casey will most probably walk free in days as she has already spent two years in jail.
