SHAMONG TOWNSHIP, N.J. (CBS/AP) — Prosecutors have filed additional animal cruelty charges against a New Jersey woman who had 44 frozen dogs and 130 live dogs at her home. The Burlington County Prosecutor’s Office says 65-year-old Donna Roberts was charged with three more counts of animal cruelty and 15 counts of unlawful confinement Thursday.

“Although the circumstances surrounding the demise of the 44 dogs that were discovered inside plastic bags in freezers remain under investigation, the deplorable and inhumane living conditions the rescued dogs were forced to endure is tragic,” New Jersey State Police Col. Patrick Callahan said at the time of the initial investigation.

Prosecutors say four of the dogs that were seized from Robert’s home in Shamong Township Nov. 13 were in critical condition, and one later died.

Malnutrition was named as a factor in the dog’s death.

Roberts was initially charged with one count of animal cruelty. She previously said she did nothing wrong.

Roberts has been ordered not to own, possess or care for animals while her case is pending.
