New Delhi, Feb. 9 -- Two men and a woman were found dead inside a parked car on the Peeragarhi flyover in northwest Delhi under mysterious circumstances on Sunday afternoon, police said, adding that while the two men knew each other, there is, as yet, no established link between them and the woman. Investigators privy to the case said they suspect the deaths may be the result of suicide by poisoning, as no visible external injuries, ligature marks or signs of struggle were found on the bodies. However, they stressed that all possibilities, including foul play, are being examined. Police said the 76-year-old man was the car's owner, who was travelling with the 47-year-old man. Both were residents of Baprola village and knew each other, officials said. The third victim was a 40-year-old woman from Jahangirpuri. CCTV footage and traffic camera recordings from adjoining area are being scanned. Police said further details would emerge after post-mortem reports and toxicology results are received. HTC...
