"It appears to be a case of suicide and all the victims are residents of Dehradun adjoining Uttarakhand state. All the deceased are members of one family," DSP Paonta Sahib Pramod Chauhan said.
The names of the deceased would be disclosed after some more verification, he added.
As soon as police received the information about bodies laying in the car in the municipal parking, it rushed to the spot and immediately opened the car to recover the bodies of a man and two women, the DSP said.
Chauhan said that after the car reached the parking this morning, the occupant closed allegedly the windows and stopped the fresh air from entering the car and probably opened a gas cylinder and died due to suffocation.
