KALAMAZOO (WKZO) -- At a police briefing last week in the Wright Brothers case, investigators said there was a third person in the fleeing pickup truck.

Sheriff Richard Fuller claimed that William Wright fired two shots at a deputy last week - and said his brother Christopher was a passenger - but the department was not saying who that third person was. 

Now, police say he is Dominique Castle and they want to talk to him. 

No charges are contemplated, but they feel he can give a credible witness account of what went on.
