Pravin Mahajan, accused of killing his brother and Bharatiya Janata Party leader Pramod Mahajan, passed away on Wednesday afternoon, sources in Jupiter Hospital in Thane said.
Doctors, who treated him, told media persons that Pravin died of sepsis and multi organ failure at 5:40pm.
According to doctors, the brain haemorrhage (diagnosed in December) triggered an infection in his body, which rapidly started affecting his organs.
They said that Pravin's condition deteriorated in the last 48 hours with his vital organs ceasing to function.
Pravin had been admitted to the hospital in December after suffering brain haemorrhage. He eventually slipped into coma and was shifted to the Intensive Care Unit.
Pravin, who was serving his life imprisonment, is survived by his wife and two children -- Kapil and Vaishali -- both of whom are college students.
Pravin, 50, who was out on furlough (special leave), was admitted to the Jupiter hospitalin December last year following bleeding in the brain. Since then, he had been in coma and never recovered, said Dr B D Pathak of Jupiter hospital.
On April 22, 2006,Pravin drove to the Worli residence of elder brother and prominent BJP leader Pramod Mahajan.
After a brief and tense conversation, Pravin, who was carrying a licensed revolver, shot Pramod and then went to police station where he surrendered.
On December 18, 2007, he was convicted by a sessions court and sentenced to life imprisonment.
In November last year, he was released on furlough. Just when the 14-day leave was about to expire, he complained of headache and blood pressure and was taken on December 11 night to Jupiter hospital in Thane.
Though he was in ICU over the past three months, his condition improved in the last 10days and was taken off the ventilator. On Tuesday night, however, his condition worsened, hospital sources added.
