North High students knew something was wrong Wednesday morning.
Kristopher Miller, a member of the Minneapolis school's support staff, wasn't there to greet them with the hugs, handshakes and fist bumps that were part of his daily routine with them.
Miller, 27, had been found shot to death after midnight on the front porch of his apartment in the 1100 block of Irving Avenue N., a few blocks south of North High, his alma mater.
Minneapolis police arrested a 40-year-old man, an associate minister at a north Minneapolis church, Wednesday in connection with the killing. The suspect surrendered to police at his home without a struggle and was booked at the Hennepin County jail on suspicion of murder.
He has yet to be charged. Police Sgt. Stephen McCarty declined to discuss a possible motive for the shooting. The Star Tribune generally does not name suspects before charges are filed.
Minneapolis schools Superintendent Bernadeia Johnson, a longtime friend of Miller's mother, went to the school Wednesday to console grieving students and staff. A profound sorrow has swept over the school, she said.
"They're trying to figure out how to deal with their grief," Johnson said from his mother's home. "People are sad."
Miller is survived by two daughters, ages 9 and 2, his mother, father and several siblings.
