Jaswant Yadav and his 35-year-old son Vijay were going on a motorbike when the incident took place at Patsera village last evening, Sub Divisional Officer of Police (SDOP) S S Tomar said.
They were returning from a court hearing, he said.
"The double murder case might be the fallout of some old enmity. The deceased, both local residents, were accused in a murder case," district Superintendent of Police (SP) Mohammad Yusuf Qureshi said.
Further investigation is on.
