FBI Chicago is searching for a man wanted on federal charges for using social media apps to extort children for sexual images and, in one instance, allegedly threatening to livestream the murder of a child and their family.

A federal arrest warrant has been issued for David Patrick Sheffield on the charge of interstate communication of threats.

Sheffield is alleged to have used popular social media applications to approach minors.

The FBI Chicago Field Office said the man solicited sexually explicit photographs and videos in return for the promise of payment.

Sheffield is alleged on at least one occasion to have made explicit threats to direct and livestream the violent murder of a child and their family, the FBI said.

The FBI said Tuesday that they are seeking the public’s help in identifying juvenile victims who may have been asked by Sheffield to produce and send explicit videos and photos.
