Baltimore Police asked for the public's help Friday in identifying victims of a
David Ralph Fisher, 42, of the 6500 block of St. Helena Street in Dundalk, was arrested Thursday after a sting operation by officers posing as a 14-year-old girl, police spokesman Anthony Guglielmi said.
He faces charges of possession and distribution of child pornography and sexual solicitation of a minor.
Detectives began investigating Fisher in November after an associate reported that she had found photographs and videos on his computer that showed adults having sex with children as young as two years old, police said.
Investigators found more than 1,000 computer folders and files of child pornography on an external hard drive, police said.
Guglielmi said police contacted Fisher by e-mail.
"We represent that we are a 14-year-old girl," he said. "We exchanged e-mails, arranged a meeting location, and this individual agreed to have sexual relations with someone who he thought was a 14-year-old girl. Turned out to be a Baltimore police detective."
Police said Fisher told them that he had looked at and traded child pornography online "for many years." Investigators believe they have identified at least some of the children in the images, but believe there are other victims, Guglielmi said.
Fisher does not have a lawyer listed in court records and could not be reached for comment.
Guglielmi gave news reporters a photograph of Fisher and asked for the public's help.
"Anyone that recognizes this individual — specifically, any young children who recognize this individual, that may have been wronged by this person — the BPD is strongly urging that you contact us," he said. "Anybody that may have been in contact with this individual in an inappropriate circumstance should really call the police. Also, anybody that feels that their children may have been victimized should also call police."
Anyone with information was asked to call 443-984-7135.
