Bengaluru: A 55-year-old businessman allegedly jumped off the terrace of his six-floor residential complex in upscale Sadashivanagar soon after killing his wife and hurling their dog from the rooftop on Tuesday morning, said a report.

The businessman was identified as Atul Upadhya, the CEO of a travel agency named NockNock Analytics located on Nandidurg Road. His wife Mamatha (53) was a homemaker.

The couple, who lived with their nephew and a pet dog in a rented flat on the fourth floor of Sycon Polaris, had no children. The incident reportedly took place after Atul’s nephew had gone to college. Upon hearing a loud noise at around 10.30 AM, security guards and housekeepers of the apartment rushed to the main gate to find Atul and his Labrador’s body on the ground.

Meanwhile, police also found the body of Atul’s wife lying in a pool of blood in the hall of their flat. There was a bloodstained dumbbell next to her, stated an officer of the Sadashivanagar police station.

A report bya leading daily quoted DCP (central) S Girish as saying, “We’ve no clue why Atul took the extreme step, besides coming across an envelope that has notes mostly about cancer.” The note reportedly said, “Cancer is a dangerous disease. This is better than cancer. This is not selfishness.”

It is not clear if Atul or his wife suffered from cancer. Moreover, the note had no mention about killing the dog, said an officer. Meanwhile, police stated that they will collect medical reports for the investigation to find out who was suffering from cancer. The carcass of the dog has also been preserved in the hospital.
