The attack appeared well planned, the police said arguing that Warekar used a newly purchased nylon rope to hang himself and had made sure that every window and door into the house was locked. He had invited his relatives to his home that night ostensibly to celebrate his daughter’s fifth birthday and even persuaded them to attend. But Warekar explicitly told his brothers-in-law not to come until Sunday. The killer apparently bolted all the doors to the house before the attack. Warekar, who is supposed to previously have drugged his relatives, used a knife to kill the others when they were sleeping. The youngest was his own daughter, a 3-month-old named Umera. Most who knew the killer described Warekar as genial and generous.
