(CNN) -- The American Civil Liberties Union has called on officials in Massachusetts and Florida to conduct independent investigations into the shooting death of a man by an FBI agent. Ibragim Todashev was fatally shot early May 22 during questioning about a 2011 triple homicide in Waltham, Massachusetts, as well as his relationship with deceased Boston Marathon bombing suspect Tamerlan Tsarnaev. Law enforcement from Massachusetts and Florida as well as the FBI questioned Todashev at his Florida home. Details about the circumstances of Todashev's death have been few, and the gaps have been filled in by media reports quoting unnamed law enforcement sources.
