Two minor girls, their mother and a teacher were found murdered at their house on Tista Road under Kadma thana area on Monday evening.

The father of the minors is the primary suspect in all four murders.

The victims have been identified as Vina Kumari (35), Rinku Ghosh (22), Diya Kumari (15) and Sanvi Kumari (11).

Deepak Kumar, 42, is suspected to have carried out the murder in the afternoon before fleeing his residence.

Rinku Ghosh, a resident of Ramjanam Nagar in Kadma had come to teach the two girls at about 11am on Monday. Her family members had become anxious and went about looking for her after she did not return home till 1pm. Her scooter was still parked at Deepak’s residence. The doors of the house were locked.

Rinku’s family members broke open the house door and found four mutilated bodies including that of Rinku lying on the floor near the kitchen.

City SP, Subhash Chandra Jat arrived at the crime scene after Kadma thana OC, Manoj Kumar Thakur had started the probe.

From the initial probe it was found that all four were killed with an iron dumbbell.

Manoj Kumar Thakur said, "From the condition of the bodies, it appears that the killings must have taken place between noon and 2 pm."

Thakur said Deepak Kumar who works in Tata Steel's Fire Brigade seemed to have absconded after the murders, adding that the reason behind the murders is yet to be established.
