A Summerville man faces multiple felony charges after investigators found child pornography on his computer, including images of infants engaged in sex acts with adults, authorities said.

State Attorney General Alan Wilson announced the arrest Thursday of Scott Douglas Marriott, 36, on 15 counts of sexual exploitation of a minor. The Berkeley County Sheriff’s Office, a member of the Attorney General’s Internet Crimes Against Children Task Force, made the arrest.

On Sept. 23, an undercover detective downloaded five video files from the suspect’s computer that were accessible to the public through a file-sharing program, Wilson said. All five files contained child pornography, he said.

On Oct. 10, deputies searched Marriott’s home on Cambell Court in the Highland Acres subdivision, which is near Sangaree schools, authorities said.

Investigators seized three laptop computers, a desktop computer and other electronic devices, Wilson said. An examination of that computer equipment revealed numerous files with videos depicting children as young as infants engaged in sexual activity with adults, he said.

“It is terribly disturbing stuff,” said Berkeley Detective Kevin Murphy, who is assigned to the task force. He said it was all the more troubling because Marriott lived close to schools.

Marriott was arrested Wednesday and charged with five counts of second-degree sexual exploitation of a minor, a felony offense punishable by two to 10 years imprisonment on each count, and 10 counts of third-degree sexual exploitation of a minor, a felony punishable by up to 10 years imprisonment on each count.

Marriott, who was released from jail on $75,000 bail, was ordered to have no contact with children under the age of 17, and no electronic communications devices (cellphones, computing devices, etc.) with the exception of a landline telephone, Wilson said.

He also was restricted from schools, malls and playgrounds, and he must not live within one mile of a school, he said.

Marriott has no previous criminal record in South Carolina, according to State Law Enforcement Division records.
