See, what happened was somebody gave Harry the works while Harry was pulling up to his abode, then this somebody, who was in the passenger seat at the time, turned his gun and killed James North who was in the back seat. Or did he give North the works first and then kill Meagher? Either way the result was the same. The car jumped the curbed and crashed into a light post. The killer got away while Meagher and North stayed put.
Why did Harry get dead? Three reasons were offered so you can pick one:
1) Gangsters from Chicago (or other eastern parts) were muscling in on the lucrative L.A. scene and it was just to bad for the local boys.
2) Harry himself was expanding into Arizona and Utah and them local fellas there weren't to keen on the idea.
3) It was an attempted robbery gone wrong.
PS
That third guy in the headline? He was an ex-boxer named Mickey Arno. He was killed about the same time and his body was found under a bridge near Long Beach. Police thought he may have been an associate of Meagher, then, after awhile, they thought that maybe he wasn't an associate of Meagher's. Could of just been one of the coincidences.
