Key Discussion Points & Insights

1. The Crimes That Shook Phoenix

• Victims: Angela Brasso (21) and Melanie Burnas (17), both attacked while cycling along Phoenix’s canals in the early 1990s.
• Details: The murders were notably brutal, with Angela having been beheaded, her head missing for ten days, and both victims stabbed multiple times.
• Impact: The crimes transformed community routines and perceptions of safety along the area’s canals.
  • Peter Van Sant (03:23):
    "Back then it was a hub of people on the canal...when we went and shot this, it's amazing. There’s no one on these anymore. That’s how lifestyles were changed."

2. The Suspect: An Everyday "Zombie Hunter"

• Brian Patrick Miller: A seemingly harmless, even gentle, father and sci-fi enthusiast known for attending conventions in elaborate costumes — his persona as the "Zombie Hunter" put him in public view, even posing with police.
  • Peter Van Sant (03:55):
    "Instead of going off and hiding under a rock somewhere, this alleged killer was out in the public posing with photographs with police officers, for goodness sakes, going to these sci-fi conventions."
• Dual Personality Allegations: Miller’s “Jekyll and Hyde” profile fascinated both investigators and journalists.
  • Amy Rosenthal (04:45):
    "Brian's lawyers said he had two sides, that he had a trauma side and he had a normal side."

3. Crime Scene & Early Investigative Theories

• Nature of the Murders: The precision and brutality led police to initially suspect a person with military or surgical training.
• Public Perception: Miller, described as "a marshmallow" and incapable of physical feats, did not fit the typical profile of a violent offender.
  • Amy Rosenthal (05:33):
    "He couldn't do one pushup. His friend said he doesn’t seem like the kind of guy who could commit these horrible crimes."

4. Critical Eyewitness: Charlotte Pottle (06:10–08:20)

• Discovery: Charlotte stumbled upon the aftermath of Melanie’s murder and called the police anonymously, only to find herself wrongly accused due to her footprints at the scene.
  • Peter Van Sant (07:41):
    "He immediately accuses her, Charlotte Pottle, of being the killer...She lives with this fear for months. But Charlotte did the right thing."

5. The Killer’s Trophy & Evidence

• “Trophy” Theory: Authorities believed Miller kept Angela’s head refrigerated as part of a premeditated plan described in his own writings.
  • Peter Van Sant (08:35):
    "He believed that the killer had kept the head in a refrigerator...one of the items on his list was to decapitate a victim and to keep the head."

6. Reporter’s Correspondence with Miller

• Post-Conviction Contact: Paula Rosa developed a rapport with Miller, even as he maintained innocence, and emails revealed both defensiveness and resignation.
  • Amy Rosenthal (09:35):
    "He said he didn’t commit these murders. I said...how is it that your DNA was found on both women? And he said, 'That's the million dollar question. If I knew, I wouldn't be sitting here, would I?'"

7. The Long Cold Case Break: Collecting DNA

• Undercover Tactics: Detectives ingeniously acquired Miller’s DNA at a Chili’s restaurant in a tense, covert operation, with undercover agents and a waitress in on the plan.
  • Peter Van Sant (13:06):
    "The manager of the Chili’s...said, I’ll be the waitress. So she played the waitress in this scenario."
  • Amy Rosenthal (12:53):
    "So, good news is he’s really hungry. Bad news is he’s not thirsty."

  • Amy Rosenthal (02:59):
    "She leans down to me...She goes, it's him. I go, what? She goes, Brian Miller, it's him."

8. Search of the “Zombie Hunter’s” Home

• The Hoarder’s Lair: Miller’s hoarded home made it almost impassable for investigators searching for weapons and stolen bikes; they uncovered “a lot of knives” and violent pornography, but not the murder weapons.
  • Peter Van Sant (14:50):
    "Brian Miller's house was like...it came from the show Hoarders."

9. Miller’s Troubled Personal Life

• Family Dynamics: Custody of teenage daughter Sarah was awarded after ex-wife Amy failed to appear in court; Amy described her duty and fear as a wife.
  • Amy Rosenthal (18:03):

    "She was afraid to be in crowds. She's always had her head on a swivel, always looking around her and still does."
