Train Photography

In a train Art is found dead. Hours later 4 people are queried?

Blonde says I am innocent, I didn't speak with Art White says I am innocent, Blonde spoke with Art Old says I am innocent, the brunette killed Art Brunette says I am innocent, one of the men killed Art The inspector says simple, 4 true statements, 4 false statements. I know the killer, very simple. Who is the killer? (Only one is involved)
