Following the housewife's speculation, that Mr. Li really is a "persistent man". He inquired within the housing community group, questioned the property management staff repeatedly, and finally managed to find a fellow resident who had been using his camera, set up at the balcony, to capture the sunrise.
Although the resident didn't live in the same building, his house was still situated near the outskirts of the community. In the automated photos taken by the camera on his balcony, a few images captured the presence of the "monster".
The moment he got his hands on the photos, Mr. Li triumphantly posted them into the housing community group, his Weibo account, and his Moments, declaring that he had found "evidence".
