Their killings prompted nationwide protests about the use of force by police but their names are missing from a federal government’s official database of homicides by officers, the Guardian reports. 
The absence of Eric Garner, Tamir Rice and John Crawford’s names raises new questions about the government’s official record of police shootings.
FBI spokesman Stephen Fischer said the database is voluntary for police departments.
“We have no way of knowing how many incidents may have been omitted,” Fischer told the Guardian in an email.
A review by the Guardian found many flaws and omissions.
“It’s just another part of the cover-up and erasing of his murder from the record,” said Eric Garner’s daughter, Erica Garner.
