Lots of people have claimed the other gunman who accompanies Jack Napier in the murder of the Wayne's is Joe Chill. Personally I always thought this was merely an attempt to try and align the origin more with the comics.
I actually always believed as a kid this second gunman was in fact......Bob the goon as a younger man!
There is no evidence either way to suggest the identity (nothing is in the credits as "Young Bob") but there seems to be clues. Jack and Bob clearly always trusted one another and you can imagine them coming up together in the underworld as teens. They also seem to be around the same ages.
The biggest evidence I have to suggest this theory is a line uttered by Bob at Axis Chemicals: "C'mon Jack let's go!". Not a special line but in the Wayne murder scene this second mugger panics and then yells: "C'mon man let's go, let's go Jack!". I doubt it was intended as a signpost for later in the film but it's pretty coincedental and something Bob actually says. The fact he has a tendency to panic also is seen in the scene where he runs off from a challenge by Batman.
