With investigations reaching a dead end in the murder of a 40-year-old housewife, who was killed on a long-distance train and found when it halted at Dadar railway station, the Mumbai Central Government Railway Police (GRP) have decided to use WhatsApp groups to find the culprit.

On December 7, 2018, Dariyabai Shankarlalji Lachheta's body was found in the ladies' compartment of the Bhuj Express, when the train was being cleaned. Since then GRP officials have questioned hundreds of suspects. They had arrested a person from Mahim who looked like the suspect seen in CCTV footage. But his blood, nails and hair samples sent to the forensic lab did not match the evidence found and they released him.
