On the night of December 28, 2018, 8-year-old Zoe Jane Kasten was one of four people killed in a shooting at a home on Whetstone Drive in St. Charles, Missouri. Police found Zoe, her 10-year-old brother Jonathan Douglas Kasten, and their 61-year-old grandmother Jane Mary Moeckel deceased in the house; Zoe’s mother, 39-year-old Kate Elizabeth Kasten, was critically wounded and later died at a hospital.

Investigators identified Richard Darren Emery, who had been living with the family and was in a relationship with Kate Kasten, as the suspect. Emery fled in a truck, exchanged gunfire with officers, abandoned his vehicle, and stabbed a woman multiple times during an attempted carjacking; she survived. He was later found bleeding in a convenience store restroom and taken into custody.

Emery was tried and in October 2022 convicted of four counts of first-degree murder, armed criminal action, and assault; the jury recommended the death penalty for the family murders and the judge sentenced him to death in November 2022. The case remains tied up in appeals. If anyone knew Zoe, her family, or has information about the night of December 28, 2018, please come forward.
