DETROIT -

A family member says one of the three American doctors killed when an Afghan security guard opened fire at a Kabul hospital was a pediatrician from Chicago who also had ties to Detroit.

Angie Schuitema is the mother of Dr. Jerry Umanos' wife. Schuitema said Thursday she learned of Umanos' death, first from her son and then from her daughter, Jan Schuitema.

The Lawndale Christian Health Center in Chicago says on its website that Umanos worked there as a pediatrician for more than 16 years before moving to Afghanistan in 2005.

He completed medical school training at Wayne State University School of Medicine and residency at the Children's Hospital of Michigan.

The shooting Thursday at Cure International Hospital in western Kabul was the latest in a string of deadly attacks on foreign civilians in the Afghan capital this year. An American nurse also was wounded.
