In September 2009, Farmville, Virginia, pastor Mark Niederbrock, 50, was killed after going to the home of his estranged wife, Dr. Debra Kelley, to check on their daughter. The visit came days after a quadruple attack at Kelley’s house that left Kelley, the couple’s 16-year-old daughter Emma, and 18-year-old Melanie Wells dead. All four victims had been bludgeoned; police say a ball-peen hammer and a splitting maul were used.

Authorities identified 20-year-old Richard Alden Samuel McCroskey III, who had traveled from California with the family group, as the suspect. McCroskey fled in Niederbrock’s car and was arrested at Richmond International Airport while attempting to leave the state. He was charged in connection with the killings.

The case centers on why McCroskey was with the family and what led to the violent escalation that night. Anyone who knew Mark Niederbrock, his family, or McCroskey and has information about their interactions in the days before the murders is asked to come forward.
