"They are penetrating," he said of Ted Franklin's eyes. "It is the worst sort of pain I have ever seen in my life.
"Words do not possess the depth in which to fully convey that emotion and what I felt when I saw it. You feel like the worst piece of scum on the planet."
The attacks all but paralysed the US capital, as people were shot at random while going about their everyday life pumping gas, buying groceries, and for one young boy, as he went to school.
Malvo repeated previous assertions that he was manipulated by the older Muhammad. But he acknowledges: "I was a monster."
When asked what he would say to victims' families, Malvo said there's no way to properly convey an apology.
"We can never change what happened. There's nothing that I can say except don't allow me and my actions to continue to victimise you for the rest of your life."
Linda Franklin's father, Charles Moore, was incredulous about the idea that victims' relatives would be able to forget about what Malvo and Muhammad did.
"What he did just destroyed my family. I'll never be able to put it aside. Never. There are things that stand out in your life that you think about. I'm 83 years old and I'll carry it to my grave."
