One of the six American troops killed in a suicide attack in Afghanistan on Monday was Joseph Lemm, a New York City police detective, the Associated Press reports.

Police Commissioner William Bratton said that Detective Lemm, who worked in the Bronx Warrant Squad, also served in the U.S. National Guard, where he attained the rank of staff sergeant.

During his 15 years with the NYPD, the AP reports, Lemm had been deployed to Afghanistan twice and Iraq once. He is survived by his wife and three children.

The Taliban took responsibility for Monday’s attack, in which a suicide bomber riding a motorcycle laden with explosives crashed into a joint NATO-Afghan patrol. In addition to those killed, one Afghan soldier and one American soldier were wounded.
