Name the fictional crime.
The crime is ...
... armed robbery.
Each word in the list ...
... is missing its first letter. There is an even number of words in each list and the (completed) words can be matched to form pairs. These pairs are common phrases that can be abbreviated by the (missing) initial letters, e.g. United Nations is abbreviated as UN. In some cases, the couple forms a single word, that is still abrreviated by the first two letters of the segments, e.g. centimetre is abbreviated as cm.

I didn't see the significance of the dots, but OP told me in the comments and now it's quite obvious to me: The dots determine the order of the pairs: Each dot below a letter lines up with a dot above a letter in the next line. (The hyphens are just there to enforce the alignment; I guess the alignment is also why the puzzle uses a monospace font.)
Anyway, we can read the abbreviations column-wise and get the motive count money, the weapons pistol and rapier and the victim Captain Farrell.
These facts ...
... point to Whiskey in the Jar, an Irish folk song made popular by The Dubliners and other bands. There are slight variations in the lyrics in each interpretation, but the general plot is the same. Here's the first stanza:
As I was a goin' over the far famed Kerry mountains
I met with Captain Farrell and his money he was counting
I first produced my pistol and I then produced my rapier
Saying "Stand and deliver" for he were a bold deceiver
Very partial solution, but it looks like...
Words are missing their first letter, and they can be matched in pairs.
