Virginia Beach police update timeline for mass shooting

Virginia Beach police have updated their timeline for the mass shooting that claimed 12 lives in May.

Police Chief Jim Cervera said it now includes exactly when city engineer DeWayne Craddock shot some of his victims in a municipal building and when he sent an email earlier that day.

The chief's statement Tuesday says police updated the timeline after Virginian-Pilot reporter Gary Harki pointed out a discrepancy and after detectives obtained previously unavailable data.

Cervera said the changes were ultimately inconsequential to that day's major outcomes. But he said the new information prompted police to re-examine every timeline entry. They found five clerical errors.

The timeline is based off cell phone data, key card access at certain doors, eyewitness testimony and physical evidence.
