The incident took place when a BSc final year student, Sharda (20) reached the college to appear for a practical exam when Special Armed Force (SAF) constable Jagdish Indorkar (24) allegedly shot her with a country made pistol.
The bullet hit Sharda in her neck after which he fired at his temple in a bid to commit suicide, the police said.
Both were rushed in a critical condition to Nagpur, but Sharda succumbed to her injuries en route, while Jagdish is battling for his life in the hospital.
He fell in love with Sharda and got very annoyed when he learnt that she would get married to somebody else on June 5, the police said.
