Whatever Kaka told were lies
If you all see or rember the flashback that kaka had one day
We saw radheshayam standing in the room and removing his nosepin hair and Bangles and. Smirking and few days back when Kaka had another flashback Kaka was chasing a radheshayam running without hair.
Which means before the car chase itself Kaka knew that it was not a woman but a man .so first part itself is a lie.
Then again in that flashback while cause radheshayam Kaka fell ya came infront of a car and stopped.
Then maayi was there in the car till she reached Aurangabad and that part was completely forgotten even by kalma nobody even maayi asked then when did she enter the car with radhey.
Maayi in sleep took the name radheya which means he was not in woman state as maayi said radhey the vehicle following u has number MH BOSS
Baapji asked ashair wether they removed number plate which means it is not Kaka who disposed the body
Last part though not so important baapji had a car of his own wow itna rich kaise hogaya . So ashahir ya theeno has a good income other then the music academy from which they earn nothing.
