COLUMBUS - Police said they identified the dog that fatally mauled a woman through animal DNA from saliva taken from her clothing.

The owner of the Rottweiler, Dr. Matthew Crawley, was charged with involuntary manslaughter and was to be arraigned Friday.

Crawley was charged in the attack on Vivian Anthony, 54, a neighbor, on Feb. 1. Anthony died on March 26 from complications associated with her wounds.

It was the second dog attack in the same neighborhood that led police to Crawley. Rose Vaughn, 45, was attacked by a Rottweiler on Feb. 24. Two men beat the dog away and she survived.

Police tracked paw prints in the snow to Crawley's back door.

Crawley owned three Rottweilers and all were seized by police and turned over to Franklin County Animal Control.

Columbus Police Detective Jim McCoskey said the DNA lab tests identified one of the dogs as the mauler of both women.

He said the testing was done by the Veterinary Genetics Laboratory at the University of California-Davis.

"I'm just glad that someone is being held responsible for the tragedy that happened," said Anthony's ex-husband, Roger Anthony.

Anthony said he has known Crawley's dogs since they were puppies - and remembered having to put them back in their pen. One of them once attacked his dog, he said.
