A Fairfax County Police investigation that began with a search warrant at an Annandale home has led to a federal child exploitation charge carrying a mandatory minimum of 20 years in prison.

Omar Garcia Bustamante, 32, made his initial appearance Wednesday in U.S. District Court in Alexandria on a criminal complaint charging him with engaging in a child exploitation enterprise.

A magistrate judge ordered Bustamante detained pending further proceedings, and a detention and preliminary hearing was scheduled for Thursday, July 30, according to Patch.

The case began in February when Dropbox submitted a CyberTip to the National Center for Missing and Exploited Children after detecting suspected child sexual abuse material uploaded to an account allegedly belonging to Bustamante. Investigators traced the account to an internet connection at a residence on Justine Drive in Annandale.

FCPD executed search warrant in April

Fairfax County Police detectives obtained search warrants for the Dropbox account and the Justine Drive residence after identifying additional suspected material beyond what was initially flagged. Detectives executed the search warrant at Bustamante's home on April 22.

During the search, investigators say Bustamante admitted using the email account tied to the Dropbox, acknowledged previously using the cloud storage service, admitted obtaining child sexual abuse material through Telegram groups, and admitted distributing that material to other Telegram users.

FBI alleges role as group administrator

After reviewing Bustamante's seized iPhone and other electronic evidence under a federal search warrant, FBI investigators allege they found evidence linking him to a private group on the encrypted messaging platform SimpleX Chat.

The charge is serious. According to the FBI affidavit, investigators identified Bustamante as one of six administrators of a group with approximately 50 participants. Federal prosecutors allege the offense occurred between at least Jan. 28 and April 21, and that administrators encouraged members to recruit others, share child sexual abuse material and actively participate.

More than 30 state felony counts dismissed

Before the federal complaint was filed, Fairfax County had charged Bustamante with more than 30 felony counts alleging violations of Virginia's child pornography statute. Virginia court records show one of those cases was dismissed through a nolle prosequi on Tuesday, a common procedural step when a case transfers to federal prosecution.

The federal charge under 18 U.S.C. § 2252A(g) carries a mandatory minimum sentence of 20 years and a maximum of life imprisonment upon conviction. The statute requires that the defendant committed qualifying offenses in concert with at least three other people.

A criminal complaint contains allegations only. Bustamante has not been convicted.

The Fairfax County Police Department had not issued a public statement on the case as of Thursday, July 30. Anyone with information about child exploitation can contact the FBI's tip line at 1-800-CALL-FBI or submit tips online at tips.fbi.gov.
