India, Sept. 19 -- New Delhi Yuvraj Singh Manchanda, a 31-year-old real estate professional, was killed allegedly by a former colleague and her partner on September 6. But for two days after his death, his family, fiancee and friends kept receiving WhatsApp messages assuring them that he would return soon.

On the night of September 6, a message from his phone read: "Main theek hoon, meri chinta mat karna, jaldi aaunga (I am fine, don't worry, I will be back soon)". The next day, another message said: "Thursday, I will call. Take care of mom." Hours later, another said: "I may have to go to Bangalore or Mumbai. My phone will be off. There's some deal. Aap pareshan mat hona (Don't worry about me)".
