From the Los Angeles Times article:
Feb. 17, 1938: Tear gas drifts from a home in the 1700 block of East 22nd Street as Los Angeles police trade gunfire with barricaded suspect George Farley. The bodies of a deputy city marshal and his helper — shot and killed by Farley as they tried to serve an eviction notice on him — lie in front of the barricaded home. Killed were Deputy Marshal T. Dwight Crittenden and Leon W. Romer, both 60.

That is some photograph. A large press camera with loads of depth of field I guess.
Though it doesn’t look like it from the crop, there is another image, just a scan from the original news print that shows the photographer with what looks to be a Speed Graphic. Pretty cool.
