In the conclusion to this two-part episode, crime reporter and author Vivian Ho reads the complete first chapter of Those Who Wander: America’s Lost Street Kids and talks about why she expanded her coverage of two murders that grabbed San Francisco's attention in October 2015 into a book.

"It just felt like a tragedy on all fronts, it was absolutely heartbreaking from the victims' perspectives — here was a young girl who was cut down as she was trying to figure out her life, as she was just starting off, and here was a man who was here to support his wife through chemo, they loved each other so much." 

"You look at these three suspects and you just wonder what the hell happened, how did we get here, how did we get here as a society, where did we go wrong," she said.
