According to the police, the driver, Rajender Singh, came to Bijender's house on Thursday night and asked him to come along as he had got a call to transport a body. Apart from the driver, three men were sitting inside the van at that time.
"The ambulance van parked outside the Euro International School was seen by the school's security guard on Friday morning. When the vehicle did not move till 7 am, the guard peeped inside the window shield and found the bodies lying in a pool of blood," said a senior police officer.
Both the victims had head injuries and their mobile phones were missing from the spot. "We have some clue and hope to arrest the killer soon," the officer said.
Bijender Singh was the only earning member of his family. He had two Sons- elder one studying in an engineering college and the younger one is at a school in Gurgaon.
