FBI team investigates cold cases (Jahi Chikwendiu/Washington Post)

Three years ago the FBI promised to investigate more than 100 unsolved civil rights killings. Now the agency is ready to close all but a handful of them, according to the Washington Post.

"There's maybe five to seven cases where we don't know who did it," said FBI Special Agent Cynthia Deitle, who is heading the bureau's effort. "Some we know; others we know but can't prove. For every other case, we got it."

Although investigators say they have solved most of the mysteries behind the cold cases, few will result in indictments. Too much time has gone by, allowing suspects to die and evidence trails to grow cold.

The Washington Post article does not name the victims whose cases are considered solved, but a list of victims on the FBI web site lists the names of those whose deaths were considered to be "fully assessed" as of October 2009.
