No one stood there with their two eyes and said, I saw him put the cyanide in the drink and give it to her.

No one said that.

That is a weak point in the prosecution's argument.

They wish they had it, but they didn't.

Of course it is.

But keep in mind, circumstantial evidence, even though most people don't believe what it really is, is very powerful.

Prosecutor Lisa Pellegrini told the court that Ferranti used his wife's vulnerability, namely her infertility, to trick her into taking cyanide that night.

Earlier in the day, Autumn had sent him this text.

I ovulate tomorrow.

He texted back, perfect timing, creatine, smiley face.

Creatine.

Creatine.

This is the solution.

This is it.

Ferrante, the prosecutor alleged, had convinced his wife that creatine could help her get pregnant.

He whipped up a poison drink knowing she'd take it as soon as she came home.

The poison drink theory was corroborated by something told later to a doctor friend of Ferrante.

And no one may have been the wiser for it if it hadn't been for a lab test that found a sky-high amount of cyanide in Autumn's blood.

Subsequent tests, the prosecutor added, were also positive for the poison.

Associate Medical Examiner Dr. Todd Lakosevic underscored that for the jury.
