BLAINE, WA (MyBellinghamNow.com) – An unexpected discovery led to a Blaine man’s arrest after being found with mass amounts of child pornography.

Whatcom County Sheriff’s Office spokesperson Deb Slater says a person reported that the suspect had dropped off a flash drive and hard drive containing the explicit images.

The person claimed the suspect was their mutual friend and thought they were borrowing the drives with movies, television shows and pornography, but weren’t expecting illegal content. Deputies seized the drives and found over 3,500 images and 170 videos of child porn.

After obtaining a search warrant for the suspect’s address in rural Blaine, they found a computer that contained similar materials.

Slater says none of the content involved images of local children.

The 33-year-old man was arrested on the morning of Wednesday, May 14 and remains at the Whatcom County Jail without bail.
