Police say a 50-year-old mother has been charged with shooting and killing her two teenage kids in an upscale suburb of Tampa, Fla because she was fed up with them being "mouthy."

(CBS/WTSP) Hundreds with heavy hearts packed the pews of a Florida church to remember 16-year-old Calyx Schenecker and her 13-year-old brother Beau, who police say were murdered by their mother, Julie Powers Schenecker, for "talking back" too much.

Choruses from Liberty Middle School and King High School, which the Schenecker kids attended, provided songs of celebration, as teachers took the podium to speak about both Beau and Calyx as stellar students.

One spoke of Beau's "great sense of humor," while another called Calyx "a wonderfully gifted artist."

The father of two Florida teens, who authorities say were killed by their mother, says he's humbled by the support he's received since his son and daughter were found dead last week.

Beau and Calyx's father, Army Col. Parker Schenecker, spoke publicly about the killings for the first time during the memorial service Wednesday night at a church outside Tampa.

The grieving father told his children's friends, "please don't forget how they lived."

According to an arrest affidavit, Schenecker shot her 13-year-old 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 Calyx in the face while the girl studied at her computer.

Investigators believe the teens "never saw it coming," said police spokeswoman Laura McElroy.
