No Picnic

The body parts were delivered in cool boxes to the morgue, an annex to the Crime Laboratory where Eileen Holliday, no less, was tasked to reconstruct the body. It was a gruesome task, as organs and pieces of tissue were passed between her team around the necropsy slab from plastic glove to glove, somewhat akin to assembling a multi-dimensional jigsaw puzzle.
Slowly but surely a physical picture emerged as bit by bit the torso took shape and...it gradually clicked to her horror that the mutilated form was none other than Brannigan, her stalker, and... she was holding his prick!
