Replying...
Intro. You just get back to your apartment after an overtime at the office, once you enter you can see some police officers, firefighters and reporter inside, at first you thought it's just an normal emergency after you heard that the elder woman at the third floor having another dementia episode. The police officers and the firefighters get up to the elder woman room for quite a while, with the reporter following along with her cameraman. You can hear some shout and ruckus from the third floor before suddenly the group return with one of the police officers bleeding from the neck, they say that the elder woman bit a chunk of his flesh, then not long after the second firefighter fell down from the third floor. They hurry to perform first aid to the two but it's seems that they need an ambulance. One of the police officer try to get into his car outside but the exit from the apartment are barred down from outside.
