MANATEE COUNTY - A Bradenton man who produced a series of violent videos of himself raping an infant and then posted them on the dark web is going to federal prison.

31-year-old James Lockhart received a maximum sentence of 70 years for producing, distributing and possessing child pornography on Thursday, according to the Bradenton Herald. He pled guilty to the charges in March.

Lockhart produced the four-video series of himself violently sexually abusing the girl between March 2016 and February 2018. He then posted them on a dark web forum using aliases “StrangeWood” and “HardWood,” according to court records.

Lockhart wrote on the forum that more videos would be produced and took suggestions, according to a plea agreement.

In addition to those posted online, investigators found more videos and images of sexual abuse of the child in Lockhart’s possession. He also bragged about abusing another 1-year-old child.

Lockhart was arrested Oct. 5, 2018, after Homeland Security agents searched his home in Bradenton and found the images on his computer.

The search of Lockhart’s residence turned up devices that contained 43 videos depicting child pornography and at least 4,000 images of child pornography. The collection included more abuse of infants and “sadomasochistic and violent conduct,” according to the U.S. attorney’s office.
