ST. LOUIS - The FBI is now investigating a deadly shooting by St. Louis police officers at the request of Police Chief Sam Dotson.

A preliminary internal investigation by the St. Louis Metropolitan Police Department said the shooting by two officers was justified. But the chief wants the FBI to have a second look at the case, and the st. Louis Police Officer's Association doesn't like it.

In April, 25-year-old Cary Ball, Jr. was shot multiple times by officers near the Edward Jones Dome in downtown St. Louis. Ball was a convicted felon in possession of a loaded weapon and was fleeing from police.

SLMPD investigators say Ball was pointing the gun at officers, but Ball's family disputes that claim and has filed a wrongful death lawsuit against the police department.

The internal investigation is still ongoing, but in the meantime, Chief Dotson wants the FBI to get involved.

"There is nothing sinister about this," said Dotson, "but I think as chief, I have a responsibility to make sure we are as objective and as thorough as possible, and that we answer any unanswered questions."

"They've already been cleared once," said Jeff Roorda with the St. Louis Police Officers Association. "How many times do they and their families have to go through this?"
