TAMPA, Fla. (AP) -- Police say the Tampa mom accused of killing her teenage son and daughter wrote a note before the shootings in which she referred to her plan as a "massacre."
Authorities say Julie Powers Schenecker bought a .38-caliber revolver the weekend before the shootings. Tampa Police spokeswoman Laura McElroy told the St. Petersburg Times the mother also noted that the three-day waiting period to take a gun home would "delay the massacre."
Police have said Schenecker shot her children, 16-year-old Calyx and 13-year-old Beau, for being "mouthy." She is charged with first-degree murder but her arraignment has not yet been scheduled.
Her husband, Army Col. Parker Schenecker, is in Fort Worth, Texas, for Tuesday's funeral for the children.
