Brother has Schizophrenia?

My brother is older than me by 9 years, and at age 23 he had his first episode. He just woke up one morning and started acting weird. Things got so bad that cops were called by neighbors and he was drag to jail for breaking a few car windows. When the cops came he resisted arrest, and I think he even acted a cop. Later we learned of his condition. I did research and got informed, I then tried educating my mom on the matter. Since then things have never been the same for him. He has been un and out of jails and mental hospitals. He hates taking his meds so he don't take them. Then he geta depressed and boom we're back in square one. He also smokes week which he isnt suppose to since he is suppose to be taking medication. He gets jealous of what I have and what he doesn't and proceed to detroy my belongings out of spite. He stole my car once for 24hrs and brought it back driving funny and adding at least 500miles or more on. He is unable to keep a job, so my mom support him. I need help
