Investigators worried about New Year's Eve celebrations

Chief Deputy Steve Martin expressed concern about New Year's eve revelers--who often traditionally fire weapons at midnight. Martin says he is hoping the public will be responsible. Martin says investigators remain confident the case will be resolved. Martin says some 3 thousand tips have now been called into a tip line. He says people are constantly being added and subtracted from a list of suspects and persons of interest. Martin would not detail how many people have fallen into either category. Martin says there has been no word from the shooter or shooters. The 60 thousand dollar reward for information leading to their arrest still stands.
