Bhanu seems to be fan of Mahesh used his name to get Pan card Driving license card at Madhya Pradesh. If any one remember  Mahesh Babu’s Pokiri  the way Mahesh kills every one with pistol at point blank may be all these  inspired him to kill Suri at point blank distance. For that reason he may have used Mahesh’s name as a part ofGurudakshina  to obtain those cards.

When so many interesting names exists why Bhanu has chosen Mahesh’s name is interesting question which can be answered by Bhanu himself.
