Dutch Schultz murder

[Dwalin2014]

Just received the book "The DA's man" by Harold Danforth and James Horan (1961 edition) about some investigations in New York since the 30s, and there is a quote in the chapter about Dutch Schultz:

It has been said that Charlie (The Bug) Workman, now in a New Jersey prison, was the gunman, hired by Murder, Inc., who had received orders from Lepke to kill off Schultz, who was making too much trouble.
It was not Workman who killed Schultz. Essex County Prosecutor Wachenfeld's report shows beyond a doubt that Schultz had been killed by a bullet from the revolver belonging to Rosencranz. He had been cut down by the very gun he had hired.
It was a sort of poetic justice.

I don't get it at all. How did the murder happen then? Rosencranz was one of the 4 victims of the hit (Dutch Schultz, Otto Berman, Abe Landau, Bernard Rosencranz). If he killed Schultz, what were Bug Workman and Mendy Weiss doing? Why would they need Rosencranz? And where did the reconstruction come from, that Workman killed Schultz in the bathroom, while Weiss killed the others in the other room? How did it happen, was Workman framed then? Also, according to the book, George Weinberg said that Dutch Schultz signed his death warrant when he killed Bo Weinberg. But wasn't he killed because he wanted to kill Dewey and put heat on the underworld this way? I don't understand anything about this hit at all anymore....

Don't know how accurate that is, but it's possible he could've been hit by crossfire, if that account is the case. But I've always heard that it wasn't the gunshot wounds themselves that kills him, but the bacteria that grew in his blood stream, from the diseased bullets. Which supposedly came from Wortman and Co. after they rubbed them down with some sort of dirty bacteria.

I would bet Lepke never thought twice about Arthur. Other than Dewey bs on top of the Murder Inc bs name one link of Lepke to Dutch. Lepke was making more money than God.
