The LA family originally wanted him dead for being disrespectful. They just never made a move because he was a very cautious mobster. Once they found out he was an informant they killed him a week later. A little motivation goes a long way I guess. Tommy Ricciardi (no relation to the NJ Lucchese mobster of the same name) shot him in a phone booth in Pacific Beach, San Diego. Jack LoCiero was the driver and replaced Bomp as consigliere. Fratianno claimed that Brooklier was on the other line when Bomp was hit, but I think that's BS. Fratianno himself was probably the one on the other end.
