New York Post style book (or maybe it was the Daily News)

Headline seen on tabloid someone else was reading on the subway:

Atl. City strangler suspect admitted killing: hooker
And I'm thinking, You don't need a colon before a list of just one thing! And then I realized that the colon is the Post's method of attribution. As in:

GAL: KIN SAW COP SLAY
So the Atlantic City strangler suspect admitting a killing, says a hooker. The suspect did not (necessarily) kill a hooker.

Punctuation means stuff!
