An Overland Park native has died in the war in Afghanistan.

The Department of Defense says 2nd Lt. Justin Lee Sisson and another soldier were killed Monday after their unit was struck by an improvised explosive device in Afghanistan.

The 23-year-old Sisson graduated from Blue Valley West High School in Overland Park in 2007. He earned a history degree from Florida State University and then completed Army Ranger School last fall.

Lee will be buried at Fort Leavenworth National Cemetery, where both of his grandfathers are buried. The date for his burial has not been determined.

He is survived by his parents and an older brother.
