MEDFORD, N.Y. (CBSNewYork/AP) — A second family of one of the Medford pharmacy massacre victims has filed a claim against Suffolk County and its police department.

The wife of pharmacist Raymond Ferguson Jr. filed the negligence claim on Sept. 14. Ferguson was among four victims killed at Haven Pharmacy on June 19.

David Laffer, 33, pleaded guilty to all charges in connection with the Father’s Day killings, including committing first-degree murder and robbing the pharmacy of thousands of prescription pills.

Also killed were 17-year-old high school senior Jennifer Mejia and 71-year-old grandfather Bryon Sheffield.

Ferguson’s wife, Viedya Quail Ferguson, is seeking $10 million in damages, according to published reports.

A negligence claim was also filed on Sept. 16. by victim Jaime Taccetta’s ex-husband on behalf of their two children.

Both families claim the county knew Laffer was troubled and should have taken his gun away before he hurt someone.

A police report released last week showed that a Suffolk County detective was concerned about Laffer having a pistol permit months before the Medford pharmacy shootings.
