(CBS/AP) Julie Powers Schenecker made a brief appearance in a Florida court room Wednesday to plead not guilty to the Jan. 27 shooting deaths of her 13-year-old son and 16-year-old daughter.
According to an arrest affidavit, Schenecker shot her son Beau in the head twice "for talking back" while they were in the family car on their way to his soccer practice. The report said Schenecker then returned to their upscale home and shot her daughter Calyx in the face while the girl studied at her computer.
Heavy security was in the Tampa courtroom Wednesday morning as Schenecker, dressed in a red jail outfit, sat with her hands shackled in front of her.
The Hillsborough County grand jury formally charged her with two counts of premeditated first-degree murder Feb. 10. If convicted, Schenecker could face the death penalty.
Authorities say the 50-year-old Tampa mother bought a .38-caliber revolver the weekend before the Jan. 27 shootings and apparently wrote a note prior to the shootings in which she referred to her plan as a "massacre."Assistant Public Defender Robert Frasier said Wednesday he intends to file a motion to freeze the family's assets until they can figure out who will pay for Schenecker's defense.
