The deceased was identified as Pinki, whose body was found lying on a hand-driven cart near a house here, Additional SP Rakesh Singh said.
There were marks on her neck that indicated that she could have been strangled, he said.
Her boyfriend, Raju, a labourer in the local vegetable market, jumped from a 40-feet-high water tank after allegedly murdering the teenager with whom he had been living for some time, Singh said.
Parents of the deceased told the police that Pinki had been missing from her house for some time and was probably living with Raju, Singh said.
However, it was not yet known what led to the murder.
