Police is yet to make any breakthrough in the case of a body being parcelled to Ajmer from from Delhi as the woman remains unidentified.
Investigators said a family from Jalandhar approached them saying it could be their daughter but after examination, it was found that she was not related to them.
Police said they were trying to locate the rickshaw puller who brought the body to the parcel office.
"We are trying to draw a sketch of the rickshaw puller. If we can locate him, it will be of great help in solving the case," the official said.
Investigators believe that the woman, aged around 25 years, was tortured and then murdered.
"She bore burn injuries and there were stab wounds on her body. We are yet to identify her," a senior police official said.
The body was parcelled by Milap Transport Roadlines from Lahori Gate to its branch in Kishangarh in Ajmer by an unidentified person. The sender has identified himself as 'B' and it has to be received by himself.
A Rajasthan police team is camping for investigations while Delhi Police is assisting them.
The body was discovered by workers of the transportation company on April 8 in their Ajmer office after foul smell started emanating from the parcel.
"The transportation company was negligent in handling the parcel. They have not entered the name of the sender and receiver properly in its register," the official said.
