Since the first time i walked into my ex house it was like this blast of disgusting smell, they have way to many pets that they can handle and none of them are fixed, or potty trained. the floor , the walls ,everything so filthy.He lives with him whole family. 3 girls, both parent, Grandma, and his stepbrother who is mentally challenged. theres roaches every step you take...holes on the floor and walls. I dont know how to put all this together but ive managed to spend full days there and its mostly because i want to see how everyone lives. I wanted to see what they did right. I discovered horrible things other then neglect of all there pets, which that is another huge story.( ive reported before but not much has been done) A horrible thing is that No ONE but the grandma takes care of the stepson... if the dad isnt home he must lay in bed. A bed so old and unconfertable. I seen him spend and entire DAY laying on the bed same positon.When he does get taken of the bed its around 12pm to 4. He is put in his special chair and is sat infront of a tv for the rest of the day. Basically Hes every day life is stay in bed till mid day if not later and then sat in front of the loud tv until its 10 or 11. they dont even own a special need Vechicle , hes is NEVER outside!...and to stand the smell and the unsanitary home he lives in....is a complete F$%^% thing. Is there something i can do? Can i report this to the police? i live in san antonio tx.
