POLK COUNTY, Fla. — A Bartow man charged in December with 15 counts of child pornography possession now faces an additional 165 charges.

The Polk County Sheriff's Office added the nearly 14 dozen charges Wednesday against William Smith, 28.

Smith has been in the Polk County Jail since his December 21 arrest. At the time, Smith's computer was seized. Deputies said a forensic examination turned up 165 files that depicted children, including infants and toddlers, engaged in sexual conduct.

Smith was formerly employed with Youth and Family Alternatives as a counselor and helped school guidance counselors and parent/guardians with truant children.

The investigation began in December, when the Sheriff's Office got a tip. Tumblr provided 48 files — images and/or videos — to the National Center for Missing and Exploited Children and deemed the files as child pornography.
