While you were sleeping, the Red Line between Belmont and Howard was shut down both directions, from 2 to 6 a.m., while police investigated the discovery of "body parts on the tracks". Only one local media outlet has any details on the death, which are few: the body probably belonged to a 30-something male who was probably struck near the Morse stop. Note to the CTA: something like this probably shouldn't be such a mystery.
