GROVEPORT, Ohio (AP) — A memorial in central Ohio has honored an American cardiologist shot and killed last month in Pakistan in front of his wife and toddler.

Police say two gunmen riding a motorcycle shot Mehdi Ali Qamar (meh-dee ah-LEE’ kuh-MER’) as his family left a cemetery after visiting relatives’ graves. He was from the minority Ahmadi (ah-mah-DEE’) sect.

About 100 relatives, friends and colleagues gathered Saturday south of Columbus to remember 51-year-old Qamar, of nearby Pickerington. The ceremony was held at an Ahmadiyya Muslim Community mosque. The Columbus Dispatch reports that speakers at the memorial remembered Qamar as a man dedicated to serving humanity.

A statement from the Ahmadiyaa Muslim Community said thousands of people attended Qamar’s funeral two weeks ago in Toronto. Qamar had dual U.S. and Canadian citizenship.
