Police said Sunil Nandan Adoor (32) and wife Megha (26) had checked into Hotel Kavery on April 11. A suspicious waiter called in the police when there was no response to his persistent efforts to get them to open their room door. The entire family remained indoors on Monday.

Police broke open the door and found Sunil and Megha hanging from the bathroom shower and ceiling fan, respectively, while their children Sakshi (3) and Abhishek (2) were found dead on the bed.
