Aug. 22, 1889: Grand ball at the Del Coronado.

A couple of French prostitutes, Louise and Vangoethan, got into a fight on Alameda Street and were brought to the police station by Officer Shannon …  Charley Robinson is the toughest Negro in the city … and a lynching in Meridian, Miss. 

I seem to recall reading about Officer Michael Shannon in Harry Carr's "Los Angeles: City of Dreams." I'll have to check.
