The killing this week of Nipsey Hussle, a rapper and advocate for the communities of South Los Angeles, sent a painful tremor throughout those neighborhoods and the music industry.

Now the man charged in his death, Eric Holder, is being represented by another Los Angeles figure: Christopher Darden, who became a household name when he helped prosecute — unsuccessfully — O.J. Simpson in 1995 for the deaths of Nicole Brown Simpson and Ronald L. Goldman.

Here’s a look at Mr. Darden, the man who famously asked Mr. Simpson to try on the bloody glove.

What has Mr. Darden been doing since the Simpson trial?

After leaving the district attorney’s office, Mr. Darden worked as a law professor, and was a co-writer on several legal thrillers as well as “In Contempt,” a behind-the-scenes account of the Simpson case that The New York Times called “powerful and affecting.”

The Times’s review noted the personal consequences that Mr. Darden said he suffered as Mr. Simpson’s lead lawyer, Johnnie L. Cochran Jr., manipulated the issue of race during the trial: “The defense lawyer’s suggestion that Mr. Darden was a token black recruited by the prosecution team for the color of his skin led to accusations, on the street, that he was ‘an Uncle Tom, a sellout, a house Negro,’ Mr. Darden says. He writes that he received death threats and was spat upon, and that his family, too, was harassed.”
