Get clues first:

$ grep "CLUE" crimescene

From Crime Scene Report #028615332953:

CLUE: Found a wallet believed to belong to the killer: no ID, just loose change, and membership cards for AAA, Delta SkyMiles, the local library, and the Museum of Bash History. The cards are totally untraceable and have no name, for some reason.

Use Ruby to find list of people with memberships to all of those.

Dir.chdir('./memberships')
Dir.open(Dir.pwd).each do |filename|
  next if File.directory? filename
  file = File.open(filename)
  instance_variable_set(:"@#{filename.downcase}", file.read.split("\n"))
end

@aaa & @delta_skymiles & @terminal_city_library & @museum_of_bash_history

This yields the following list:

Deron Estanguet
Stephanie Adlington
Aldo Nicolas
Sonata Raif
Jeremy Bowers
Didier Munoz
Nikolaus Milatz
Marina Murphy
Krystian Pen
Mary Tomashova
Kelly Kulish
Matt Waite
Monika Hwang
Emma Wei
Liangliang Miller
Jacqui Maher
Jamila Rodhe
Andrei Masna
Tamara Cafaro
Brian Boyer
Dalibor Vidal
Mike Bostock
Augustin Lozano

From Crime Scene Report #912464709392:

CLUE: Footage from an ATM security camera is blurry but shows that the perpetrator is a tall male, at least 6'.

Using ./people, we can elimnate females from that list.

Deron Estanguet
Aldo Nicolas
Jeremy Bowers
Didier Munoz

Krystian Pen
Matt Waite
Liangliang Miller
Andrei Masna
Brian Boyer
Dalibor Vidal
Mike Bostock
Augustin Lozano

From Crime Scene Report #575776622208:

CLUE: Questioned the barista at the local coffee shop. He said a woman left right before they heard the shots. The name on her latte was Annabel, she had blond spiky hair and a New Zealand accent.

In ./people, search for Annabel.

$ grep "Annabel" people

There are two females listed. Review both interviews. From interview-699607:

Interviewed Ms. Church at 2:04 pm. Witness stated that she did not see anyone she could identify as the shooter, that she ran away as soon as the shots were fired.

However, she reports seeing the car that fled the scene. Describes it as a blue Honda, with a license plate that starts with "L337" and ends with "9"

At this point, we merely need to check our culled membership list from above against the DMV records. Anyone that drives a Honda, a blue car, or a car with a license plate that matches the partial is a suspect.

Deron Estanguet -- Red Nissan, no partial match, too short
Aldo Nicolas -- Pink Cadillac, no partial match, too short
Jeremy Bowers -- Blue Honda, partial match, close in height
Didier Munoz -- White Fiat, no partial match, too short
Nikolaus Milatz -- Yellow BMW, no partial match, close in height
Krystian Pen -- Pink Volvo, no partial match, too short
Matt Waite -- Blue Toyota, partial match, close in height
Liangliang Miller -- White Hyundai, no partial match, too short
Andrei Masna -- Teal Mazda, no partial match, too short
Brian Boyer -- Blue Jaguar, partial match, probably too tall
Dalibor Vidal -- Blue Jeep, no partial match, somewhat close in height
Mike Bostock -- Teal Honda, partial match, somewhat close in height
Augustin Lozano -- Red Toyota, no partial match, somewhat close in height

Our reasonable suspect list now looks like this:

Jeremy Bowers -- Blue Honda, partial match, close in height
Matt Waite -- Blue Toyota, partial match, close in height
Andrei Masna -- Teal Mazda, no partial match, too short
Brian Boyer -- Blue Jaguar, partial match, probably too tall
Dalibor Vidal -- Blue Jeep, no partial match, somewhat close in height
Mike Bostock -- Teal Honda, partial match, somewhat close in height

After reviewing interviews, Jeremy Bowers sticks out. He's missing, and everyone else checks out after more research. This seems like our guy.

echo "Jeremy Bowers" | $(command -v md5 || command -v md5sum) | grep -qif /dev/stdin solution && echo CORRECT\! GREAT WORK, GUMSHOE. || echo SORRY, TRY AGAIN.
CORRECT! GREAT WORK, GUMSHOE.

Solved!
