A Minneapolis teenager accused of fatally shooting another teen in the back earlier this month will be tried as an adult on a charge of second-degree murder.

Malcolm Maghundi Jackson, 16, waived adult certification proceedings Monday. He is expected to appear Tuesday before District Judge Mark Wernick in Hennepin County District Court.

Jackson is charged in the June 1 slaying of 16-year-old Trequan Sykes. The complaint says Jackson, angry about an earlier fight with Sykes' brother, allegedly stashed a revolver outside South High School in Minneapolis and then confronted Sykes in an alley in their neighborhood.

Sykes was shot in the back behind his home as he tried to walk away, witnesses said. Witnesses said Jackson also threatened Sykes' brother and sister with the gun.

Sykes was found in the entryway of a nearby apartment building. He died at Hennepin County Medical Center.
