The most sensational murder trial of a two-year-old Caylee Anthony concluded Tuesday with a verdict of Casey, Caylee's mother, found 'not guilty' shook the nation. Americans across the expressed their fulsome anger in social media.

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 as missing.

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.

Some have raised the question whether the Jury would have let them go if they were Black. If she were black teenage single mother, then she would have been convicted. But plenty of other whites who killed their children are also convicted.

Diane Downs was just as sensational and unsympathetic; who shot her three children, killing one, and then told police a stranger had attempted to carjack her and had shot the children. She was sentenced to life in prison.

But according to statistics from deathpenaltyinfo.org, there are some interesting facts about death sentences:

* A total of 167 death sentences have been imposed upon female offenders from 1973 through late-2010, which is just 2 percent of all death sentences during the time period.

* Of the 167 death sentences imposed since 1973, only 55 women remained under sentences of death in eighteen states and under federal jurisdiction as of late 2010, which comprise only 1.7 percent of the approximately 3,261 persons currently on death row.

* Currently on death row are 24 women who killed their husbands or boyfriends, and another 11 women who killed their children. One other woman killed both her husband and her children, and three other women killed a young niece, nephew, or child in their care. These 29 women account for over half of the 55 women now on death row.

* Out of 167, white offenders scored 110 and Black offenders scored 42 only, while Latin offenders and America Indian offenders were 11 and 4 respectively.

* The annual death sentencing rate for female offenders during the last decade has averaged four per year.

*The most recent execution of a female offender was that of Teresa Lewis in Virginia on September 23, 2010.
