Atlanta - The wife of an unemployed Georgia doctor charged with fatally shooting a Yale University physician said Wednesday that she was shocked over the death.

Lan Ma, whose husband, Lishan Wang, is being held on $2 million bail in Connecticut in the death of Vajinder Toor, released a statement through an Atlanta attorney.

"At this moment, all I want is to protect my children," said Ma, who lives with her three children in Marietta just north of Atlanta. "I give my condolences to Mrs. Toor and her son. May God help us to overcome this hardship."

Ma hasn't spoken to her 44-year-old husband since he was taken into custody shortly after Toor was gunned down Monday in front of his Branford, Conn., home, said family friend Christopher Pu. Pu said Ma is making arrangements to travel to Connecticut to see Wang, though she doesn't yet know when she will be able to go.

Police say Wang and Toor worked together at a New York City hospital before Wang was fired. Police say they found documents on two other former colleagues of Wang's in his van, along with 1,000 rounds of ammunition, Google directions to the shooting location and a picture of the victim.

Police say Wang also shot at Toor's pregnant wife, but missed. Wang is charged with murder, attempted murder and firearms offenses.

After leaving New York, Wang was hired as a postdoctoral fellow for the Morehouse School of Medicine in Atlanta in February 2009, but officials there declined to say what he did at the historically black medical school.

Spokeswoman Cherie A. Richardson said Wang quit in February. She declined further comment, saying Morehouse School of Medicine is not involved in the investigation into Toor's death.

In a statement released Tuesday, Richardson said Morehouse medical school officials were horrified by the incident.

Toor was a postdoctoral fellow at the Yale School of Medicine who was working with the infectious disease section of Yale-New Haven Hospital.
