Seattle police arrested a suspect Wednesday who they say carjacked a beloved 80-year-old dog walker who died after she struggled to protect the dogs, was pushed out of her car and was struck by the vehicle as the suspect fled.

The 48-year-old suspect was identified after someone reported a man hurting a dog in a park about 5 miles (8 kilometers) away. Officers responded and found Ruth Dalton’s car nearby and were able to get fingerprints from her cellphone, Seattle police Deputy Chief Eric Barden said during a press conference announcing the arrest.

The suspect, who had stabbed the dog to death, was later arrested near his home by a SWAT team, Barden said. He was carrying a knife that had blood on it and the keys to Dalton’s Subaru, he said.
