A memorial service is scheduled for Wednesday for a Michigan soldier killed in an explosion in Afghanistan.

The Defense Department says 25-year-old 1st Lt. Todd Lambka, of the Detroit suburb of Fraser, died Aug. 1 when an improvised explosive device detonated in Paktika province. The military says Pvt. 1st Class Jesus Lopez, 22, of San Bernardino, Calif., also was killed.

A plane carrying Lambka's remains arrived Saturday at Selfridge Air National Guard Base, where it was met by members of his family.

Lambka was a West Point Academy graduate in 2010.

The memorial service is scheduled for 7 p.m. at Wasik Funeral Home in Macomb County's Shelby Township.
