A Wareham man has been arraigned on charges he possessed child pornography, Plymouth County District Attorney Timothy J. Cruz has announced.

Brandon Dalomba, 35, of 56 Swifts Beach Road was arraigned in Wareham District Court on June 23 on four counts of possession of child pornography. Dalomba was arrested earlier that day by Wareham Detectives on an outstanding warrant for possession of child pornography.

Dalomba pleaded not guilty and was held on $40,000 cash bail, with the conditions that if he makes bail, he will be placed on a GPS monitoring bracelet and ordered to have no contact with children under the age of 18 or electronics.

Dalomba’s arrest and arraignment followed a several months-long investigation by the Massachusetts State Police Computer Crimes Unit/Internet Crimes Against Children Task Force.

The National Center for Missing and Exploited Children was advised of two incidents of child pornography on Chatstep.com. Chatstep.com had submitted two cyber tips to the National Center for Missing and Exploited Children that photos, which allegedly contained child pornography, had been uploaded and posted during a chat and the person uploading the images lived in Plymouth County, according to officials.

The State Police task force reported that it had located a computer that was sharing files containing images and videos of child pornography. The computer’s location was traced to a home in Wareham and on June 16, State Police sought and obtained a search warrant for that address. State Police seized four primary desktop hard drives, one laptop, desktop hard drives, a ZTE 981 Cellphone and other additional storage media equipment and devices.

As part of the investigation, forensic examiners determined that there were numerous digital files depicting child pornography that had been downloaded from a computer connected to Dalomba’s cellphone.

The case was investigated by the State Police Detectives in the Plymouth County District Attorney’s Office and the State Police Computer Crimes Unit/Internet Crimes Against Children Task Force.
