TAMPA, Fla. (WFLA.com) - "I was planning for a Saturday massacre," Julie Schenecker wrote in a journal after allegedly killing her two children.

The 53-year-old
Tampa mother is charged with two counts of first-degree murder for the deaths of her two children, her 13-year-old son Beau and 16-year-old daughter Calyx, in their Tampa home in January 2011.

The chilling testimony came at the end of the day Monday from Tampa Police Department Crime Scene Technician Matthew Evans. He read statements from Schenecker's journal, which appeared to lay out a plot to kill herself and her children, then detailed how she fatally shot her two children with a gun she purchased the week of their deaths. 

Evans read from Schenecker's journal, "I was hoping it would be tonight... I cannot stand waiting for 5 days." She wrote, "I will pick up the gun on Thursday... Calyx, she gets it first. Don’t know whether I will first turn on the light or have her blind... I'm nervous."
