An Orange County woman and her son are now facing additional animal cruelty charges after an initial investigation resulted in 57 dogs and puppies being seized from two properties off Alexander Drive earlier this month.

A release from the Orange County Sheriff’s Office said 65-year-old Cynthia Riggan turned herself in on Wednesday night “facing multiple charges of animal cruelty.” Authorities said Riggan’s son – 35-year-old Taylor Doar – is facing the same charges and was arrested on Thursday afternoon.

The two are facing 16 felony and 37 misdemeanor charges.

Two independent sources initially notified law enforcement of the conditions that led to the charges, authorities said, which included malnourished animals, parasitic infestations and unsanitary conditions.

The additional charges come as the seized animals have been undergoing veterinary exams. One puppy died from complications of hookworms and coccidia, Orange County Animal Services director Bob Marotto said in the release.

Officials said the rest of the animals are “generally doing well” and continue to receive additional medical care. But the influx of animals “has put a strain on resources,” animal services communications specialist Tenille Fox said.

“If anyone would like to help, material and monetary donations are much appreciated.”

Donations can be made through the animal services’ website. Officials said the animals will remain at the Eubanks Road facility “until either the resolution of the case or until such time as they become the property of Orange County.”
