Aman, a neighbour of Gaurav, said: 'We could not find any clue to Gaurav's whereabouts despite searching at various places and inquiring from many of his friends. At around 10.30 p.m. I saw Gaurav's car in the market of Sector 19.'

'I saw two of them sitting inside the car but when I knocked at the door nobody opened it. Sensing something wrong, I broke the window and found them lying unconscious. With the help of my friends I immediately took them to the hospital and informed the police,' he added.

Aman said that AC of the car was on and a very foul smell was coming out of it.

The couple was declared dead by the doctors.

'Gaurav and Alisha loved each other and wanted to marry but their family members were against this,' said another neighbour.
