Tsarnaev was an avid Instagram user, but deleted the account before he carried out the Boston Marathon bombing with his older brother Tamerlan, who was shot and killed in a firefight with officers in Watertown, Massachusetts.
Instagram is a popular photo-filtering app that was bought by Facebook for $1 billion. The company's Terms of Service agreement that all users need to sign indicates that Instagram may hand over your private data if it's requested by the authorities.
The Instagram account has been taken down and we couldn't get copies of the images Tsarnaev uploaded. If you have a screenshot or some saved pictures, email us at email@example.com.
