A former Massachusetts police chief acquitted of charges connected to the 2008 death of an 8-year-old boy at a gun show wants unrelated firearms charges dismissed.

Former Pelham Chief Edward Fleury has pleaded not guilty to charges of assault with a dangerous weapon and improper storage of firearms for allegedly pointing a loaded handgun at a friend outside a Belchertown bar in September and improperly storing 22 guns in his home.

Fleury's lawyer told a judge Tuesday that he plans to file motions to dismiss the case and suppress evidence. Attorney Patrick Melnik Jr. did not comment after court.

The trial is scheduled for September.

Fleury was acquitted of manslaughter in the death of the Connecticut boy who accidentally shot himself with an Uzi at a gun show sponsored by Fleury's firearms training company.
