An Elgin police officer shot and killed a dog that was violently attacking its owners, a man and woman, while they were walking it on Thursday evening. Witnesses reported that the dog became aggressive after seeing another dog, turning on its owners and inflicting severe injuries on the woman, including deep lacerations. Despite attempts by the officers to disengage the dog, it remained clamped onto the woman's arms, prompting the officer to use lethal force to protect the victims. Both owners were hospitalized with serious but non-life-threatening injuries, and police rendered immediate first aid following the shooting. Witnesses praised the police for their quick response, suggesting that the intervention likely saved the woman's life. No further details about the incident have been released by the Elgin Police Department as of now.
