A visibly shaken Julie Schenecker is transported from Tampa Police headquarters to Orient Road Jail.
Tampa, Florida - We're learning more about the Friday morning when Tampa Police responded to a welfare check at a Tampa Palms home, only to find two teenagers shot to death.
A search warrant says when officers arrived at the Schenecker's Ashington Reserve home, they found the mother, Julie, unconscious on the porch. Her white robe was covered in dried blood.

The reason, police say, is because she shot her children to death. Inside the house police say Julie left a note detailing why she killed her kids.
In the master bathroom, they found 15 bullets and five casings. In the master bedroom, they found more bullets in a Smith and Wesson box with an instruction manual.
Police say it was Thursday night when Julie Schenecker, 50, shot her 13-year-old son Beau right around the time he was supposed to be at soccer practice. They say she fired a shot through the windshield of their SUV before she killed him, then left his body in the car in the garage.

She then allegedly went upstairs to her 16-year-old daughter's bedroom, where she shot Calyx while she was doing homework at her computer. Schenecker moved her daughter's body to the bed.
The search warrant shows stunning similarities: both children shot twice in the head, both bodies wrapped with blankets.
