LEE COUNTY, Fla. - Today, opening statements are expected to start in Andrew Castor's trial.

The Cape Coral man confessed to stabbing his neighbor, Bianca Interiano, to death back in 2009. However, last September a judge threw out the confession after defense attorneys say police continued to question Castor after he requested an attorney.

Castor faces first-degree murder and burglary charges. The defense team says at least one doctor agrees castor was insane at the time of the crime.
