"The Five Days That Shook a City" from Mr. District Attorney #1 (National, 1948) by Sam Citron(?) and Charles Paris
A popular radio drama that lasted from 1939 to 1951 (and then briefly on television), Mr. District Attorney also spawned a 67-issue comic book series, running from 1948 to 1959, so much longer than even the show's syndicated broadcasts (which didn't go beyond 1953). Each issue, so far as I can tell, featured several full cases prosecuted by the originally nameless D.A. (dubbed Paul Garrett when TV got involved).
