A Florida woman was arrested Wednesday after officials said she was seen trying to drown a dog in the ocean but was stopped by witnesses.

Marilynne Jones, 70, was at the Lighthouse Point Park at Ponce Inlet in Daytona Beach on Wednesday when witnesses said they saw her pulling on a cocker spaniel as it was trying to get out of the ocean, the Daytona Beach News-Journal reports. Officials said the dog was unconscious when witnesses grabbed it out of the water.

"I observed the lady with a dog on a leash in the water and the dog was trying to get out of the water and she kept pulling it back into the water," witness Edvaldo Silveria said.

The dog had "stopped breathing and was foaming at the mouth," and witnesses said Jones was unfazed by the entire ordeal and was laughing at one point, the News-Journal reports.

"A lady here drowned her dog on purpose and she’s laughing about it!" the caller to 911 dispatch said, according to the News-Journal. "It's just breaking my heart. I have two dogs."

The dog, whose name is Gracie, was taken to a veterinarian, where she is still being held. Jones was arrested and charged with felony cruelty to animals.
