A Florida woman, who has been charged with killing her two 'mouthy' teenage children, has been denied bail.

Julie Schenecker, 50, was arrested last Friday and charged with two counts of first-degree murder in the deaths of her 13-year-old son, Beau Powers Schenecker, and her 16-year-old daughter, Calyx Powers Schenecker at their home in Tampa.

She has been accused of shooting her son twice in the head in the family car for talking back. The Army wife then drove home and allegedly shot her daughter in the face.

At this point miss, you're obviously going to be held without bond, Circuit Judge Walter Heinrich said.

I assume in the future, the defense will request the appointment of doctors, said Judge Heinrich. That's something that will take place after they file the appropriate documents.

She did tell us that they talked back, that they were mouthy, Laura McElroy, Tampa police spokeswoman, told WTSP. But I don't think that will ever serve as an explanation to the rest of us of how you could take a child's life.

Schenecker spent Saturday and part of Sunday at a Tampa hospital in an intensive care for a pre-existing medical condition.

Jail officials said it was this medical condition that apparently left her visibly shaken and contorted as they escorted her from the Tampa Police department on Friday.

Dressed in a prison suit with the word Inmate on the front, she made her first court appearance Monday morning at the Hillsborough County Courthouse in Tampa.

According to the Tampa Police statement, they received a phone call from the suspect's mother in Texas at 7:39 a.m. on Friday, January 28.

Schenecker's mother was concerned that she could not reach her daughter who she believed was depressed.

When officers arrived at the family home at 7:45 a.m., they found the suspect on the back porch with blood on her clothing, the statement said.

Officers found the 13-year old male victim shot to death in an SUV in the garage. They later discovered the 16-year old female victim shot to death in an upstairs bedroom.

During a post Miranda interview with detectives, the suspect confessed to killing her two children. She described the crimes in detail, the Tampa Police said.

Preliminary investigation indicates that the victims were killed on Thursday evening. However, the Hillsborough County Medical Examiner would determine the exact time of death.

Meanwhile, Schenecker's husband is on his way back to the United States. U.S. Army Colonel Parker Schenecker, 48, was working in Qatar when he received news of his children's murders. He is assigned to the Central Command headquarters at MacDill Air Force Base in Tampa.

A memorial page for Calyx and Beau Schenecker has come up on Facebook.
