YG joins a long list of entertainers who have publicly mourned Nipsey's death. The Crenshaw native was gunned down Sunday afternoon in the parking lot of his Marathon Clothing store. Authorities captured the suspected gunman, 29-year-old Eric Holder, on Tuesday in Bellflower, California. Officials said they believe Nipsey and Holder had a dispute of "a personal nature" shortly before the shooting. 

Holder remained in custody as of Wednesday afternoon, with his bail set at more than $7 million. The charges against him have not been announced.
