Branford, Conn. police say 44-year-old Lishan Wang is charged with murder, attempted murder and firearms offenses in the fatal shooting  outside Toor's home.  Police say Wang also fired at Toor's pregnant wife, but she was not struck.

An employee of Kingsbrook Jewish Medical Center in New York said the two men clashed at that facility a few years ago after Wang left his post at the intensive care unit and was not reachable for a few hours. The employee said Toor reprimanded him and that Wang threatened Toor in front of other employees.

The employee spoke on condition of anonymity because of the ongoing murder investigation.

The alleged gunman, who's from Beijing, was last known to be living in Marietta, Ga.  Police said the shooting was not random or connected with Toor's job at Yale.

Wang is being held on $2 million bond.
