I was gong to say “El Paso” too.
But now that it’s taken, I’ll say “So Long Bernie” by the Lowest of the Low, about a guy who sees one of his best friends on the news, arrested for raping and murdering a girl.
Another John Hiatt song about robbery:* Trudy and Dave*, about a couple who knock over a Laundromat and “got away clean.”
From the same album, more robbery from “Trudy & Dave”.
They seem to be the Leopold and Loeb of pop music.

Riders on the Storm – The Doors
*The Green, Green Grass of Home *-- Tom Jones
The Killing of Georgie – Rod Stewart
The Night the Lights Went Out in Georgia – Vicki Lawrence
Abraham, Martin and John – Dion

I hear they got away clean.

Uhm, “The Way” was written they heard about an older couple who disappeared on their way to a Pioneer Day festival. It turned out later the reason that they didn’t make it was because they were dead.
Hit-man song (I think)
Just a Job to Do by Genesis
Unknown crime
Don’t Lose My Number by Phil Collins
From the same album:
Abetting escape of a fugitive: “State Trooper”
As someone already pointed out, folk music is full of felonious conduct. Archivist Alan Lomax devoted an entire album to prison songs. “Whiskey In the Jar” is about highway robbery. “Little Musgrave” concerns adultery and murder by dueling. “Jesse James” is about Jesse James. Lots of Irish and Scottish music celebrates behavior the English called murder, treason and rebellion at the time it happened. --Of course, if we’re going to include political crime, at least some American Civil War music would qualify. And probably some from the American Revolution. 
Hostage-taking & kidnapping situations are addressed by the various songs titled “Stockholm Syndrome” (not to mention the two albums and a band that also are named that).
Child Abuse: Uncle Ernie, the Who
Lots by Dylan
The Lonesome Death of Hattie Carrol
The Ballad of Hollis Brown
John Wesley Harding
Memphis Blues Again (Caught without a ticket, and discovered beneath the truck.)
Arson: Norwegian Wood
Burglary: Boston Burglar by Cat Mother and the All Night Newsboys
Murder: Do It Again, Steely Dan
But not “Parchman Farm” - I ain’t never done no man no harm.
Independence Day-Martina McBride
Spousal abuse, arson, homicide.
Does “Run for Your Life” by the Beatles count?
“I’d rather see you dead little girl, than to be with another man.”
No list about school shootings is complete without the classic “Jeremy” by Pearl Jam.
Drug Songs:
Koka Kola - The Clash
Waiting for my man - Velvet Underground
I hadn’t known that. But judging by the lyrics alone, it seems they abandoned their kids: Fastball - The Way lyrics | LyricsFreak
