I think it is either tie dye kid or his father who did it. Strong possibility of both too. It goes back to what the Detective said. You got to explain “the who, how, why, and why now” The who (tie die kid) how (he knows how to sneak into apartments him and his gf did it before) Why (revenge for being framed) and Why now (he literally just got out of jail) and him being close to the Selena is why he knew he needed to stab Steve Martin’s girl because she wouldn’t leave shyt alone. He wants it framed on the deaf kid for multiple reasons. I think the Father is his son’s accomplice. He has just as much reason to want revenge and would have rat poison as a building super.
