Branford police spokesman Lt Geoffrey Morgan said that 34-year-old Vajinder Toor suffered multiple shots in the parking lot outside the condominium in the New Haven suburb on Monday, Apr 26.
The victims's former colleague Dr Lishan Wang (44) at Kingsbrook Jewish Medical Center in Brooklyn has been accused of the killing by the police.
Wang also tried to kill Toor's wife, who came out of the house on hearing the sound of gun shots.
The accused has been charged with murder, attempted murder and firearms offenses. Currently he is being held on a bail of two million dollar.
According to New York Times report the Toor was shot when he was walking towards his car in the parking lot just before 8 am on Monday, Apr 26.
Toor, postdoctoral fellow at the Yale School of Medicine, was working with the infectious-disease section of Yale-New Haven Hospital.
He had graduated from New Delhi, India and joined Kingsbrook Jewish Medical Center in Brooklyn in 2008.
Authorities said that the accused has been arrested based on the details provided by the witnesses.
Suspecting that Wang's old enmity could have triggered his action, the authorities said that the accused had a history of confrontations with the Toor as well as with other colleagues.
Wang had filed a federal lawsuit filed in Jul, in which he claimed of that Chinese residents were singled out and verbally humiliated by medical staff, including a "Dr Vajinder," the chief resident for the Department of Medicine.
He was a member of Kingsbrook's medical residency training program which began from Jul 2006, but he was thrown out from it two years later.
