ORLANDO, Fla. (AP) — The trial of a Florida mother charged with killing her 2-year-old daughter has resumed in an Orlando courtroom, a day after her attorneys sought a mistrial and a judge ruled she was competent to continue the trial.

The first witness called Tuesday morning was a former team leader of Texas Equusearch volunteers who searched for Caylee Anthony.

On Monday, Casey Anthony's attorneys asked the judge to select a new jury. The attorneys sought the mistrial based on a ruling by a federal judge in Miami last week that declared Florida's death penalty unconstitutional.

Anthony has pleaded not guilty to first-degree murder and could face the death penalty if convicted of that charge.

The trial judge ruled Anthony is competent Monday after her attorneys asked that she get a mental evaluation.
