Scary stuff: The doctor who stands accused of murdering a Yale physician on his doorstep earlier this week had plans to carry out several more murders in Brooklyn, according to authorities. After allegedly murdering his former supervisor, Dr. Vajinder Pal Toor, cops claim that the suspect, Dr. Lishan Wang, planned to attack at least two other former colleagues at the Brooklyn hospital from which he was canned in 2008. Wang was allegedly carrying three firearms and 1,000 rounds of ammo. “What truly scares me is he could have gotten into this place and initiated a massacre," said one doctor at the Kingsbrook Jewish Medical Center. Wang was fired in 2008 for hurling an ethnic slur at Toor.
