"Casey Anthony is a unique individual. A close inspection of her case clearly supports not filing a notice seeking death," attorney Terence Lenamon wrote in a report obtained by the Orlando Sentinel.
* The techniques used to analyze hair and air samples from the trunk of Anthony's car to prove evidence of a body are "novel, experimental, in the early stages of development, inconclusive and highly susceptible to mishandling," Lenamon wrote. Even if the evidence is enough for a guilty verdict, it would not be enough to support the death penalty, according to the report.
* Details of the Anthony case are insufficient to justify the death penalty, the lawyer wrote. She doesn't have a criminal record. There is no history of child abuse. The crime was not cold, calculated and premeditated. No one knows how death might have happened -- if at all. In the months leading up to Caylee's disappearance, Anthony's behavior was described by friends and family as "erratic and not entirely rational."
* Filicide -- the act of a parent killing a child -- is different from other homicides. The underlying reasons why mothers kill are complex and can be divided into various categories.
* Juries are more likely to show mothers mercy. The report mentions Andrea Yates, a Texas mother who drowned her five children. She was sentenced to life in prison but later sent to a mental hospital. Susan Smith, the South Carolina mother who drowned her two children in a lake, got life in prison.
* Experts will likely agree that Anthony was "suffering from episodes of extreme emotional distress and disturbance since her daughter's birth," the report said. Even the lack of emotion after her child's disappearance and the arrest "is not normal," Lenamon wrote.
* Anita Simmons, an Orange County woman who beat her 8-year-old daughter to death, got 42 years in prison, the report said. Lenamon also cited other examples around that state that also led to life sentences.
"A careful consideration of the totality of the circumstances in this case leads to a clear conclusion that filing a notice of the death penalty is not the right thing to do," he wrote.
