WINONA, Minn. – A police investigator has been assigned to sort out a man’s report that he was assaulted by a girlfriend of his ex-girlfriend. “What assault?” the women told the responding officer. They denied getting physical. The man had called police about 3:30 p.m. The man said he had gone to his ex-girlfriend’s apartment on the 700 block of Jimmy Carter Place on the Far West End to drop something off. There, he said, as he approached his ex-girlfriend, her friend — another woman — grabbed his neck and pushed him against bis car. The two women recounted the incident differently. They said the man was the aggressor. One question for the continuing investigation is whether any surveillance or doorbell cameras caught what really happened.
