Martin family attorney: Prosecution "covering all the bases" with third-degree felony charge

12 days of trial, 56 witnesses, 200 plus exhibits, but did the prosecution prove their case beyond a reasonable doubt?

Today, the state tried to introduce a lesser charge at the last-minute of third degree felony murder –child abuse, but the judge didn't buy it.

"I went back and I looked at all this and I don't think the evidence supports a charge to the jury for 3rd degree felony murder for child abuse charge, so I'm not going to give that any instruction," Judge Debra Nelson said.

Zimmerman's assumptions led to death, prosecutor argues

Was it a sign of desperation or is the state just trying to cover all bases?
