An elderly couple were robbed and murdered in their three-bedroom apartment in Bandra, on Thursday. The police suspect a domestic help killed them.The couple have been identified as 85-year-old Nanak Gopaldas Makhijani and his 71-year-old wife Daya Nanak Makhijani. They lived in their Khar apartment with a live-in maid. The couple are survived by two sons, both of whom live abroad and who have been informed of this tragic incident.On Thursday morning, at 9am, a part-time help who worked at the Makhijanis rang their doorbell but there was no answer. She informed the watchman, who tried contacting the flat using the intercom. The watchman also called Nanak’s mobile and got no response.At this point, the watchman contacted the building’s chairman who instructed the housekeeping staff to find a way into the flat. The staff used a ladder to reach the first-floor flat and found the couple’s bodies in their bedroom. The police were immediately informed.The police said preliminary investigations suggest the couple were strangled to death in their sleep, possibly using a dupatta. The motive is believed to be robbery since some gold ornaments are missing. The police suspect the Makhijanis’ live-in maid, who was hired approximately two weeks ago, committed the crimes. She was not in the flat when the bodies were found.“There are no CCTVs in the building to ascertain the exact time of the incident, or when the servant left the building premises. We are in the process of questioning the watchman to figure out who the servant was and when the servant left from the building,” said a police officer, requesting anonymity. The Makhijanis employed four domestic help, of whom only one lived with them. According to police officials who did not want to be named, the part-time help are also being questioned. The live-in maid had been recommended for the job by the watchman, said the police. Investigations are on to ascertain if she had an accomplice.
