Joly was strangled to death and his body hung in the temple premises yesterday, police said.
The deceased was allegedly in a relationship with Priti against the wishes of her family and the two had eloped on May 4.
The girl's father Vinod Kumar had subsequently lodged a complaint with the police, but the two returned in the meantime having been promised marriage, they said.
A case of murder has now been registered against Kumar, his brother Bhupendra and two others, they said, adding that the search is on for the accused.
