Daniel "Dan" Cooper was a warehouse worker for the Kerb!am shipping corporation. He had a daughter on Kandoka whom he did not often get to see. He channelled most of his wages into an education fund for her and wore a necklace that she made.
He was killed after being used as a test subject for Charlie Duffy's exploding bubble wrap and his remains were liquidised along with the rest of the missing people. His necklace was later found by Yasmin Khan, who later returned it to his daughter. (TV: Kerblam)
