A 62-year-old Baton Rouge lawyer charged Tuesday by federal prosecutors with receiving child pornography over a three-year period will plead guilty, his attorney said.

William Steven Mannear faces a mandatory minimum of five years in prison and up to 20 years if convicted as charged, U.S. Attorney Walt Green said in a prepared statement.

Prosecutors allege in a bill of information that Mannear used a computer to knowingly receive child porn from August 2009 through September 2012.

Jim Boren, who represents Mannear, called him “a good man, a good family man, and a good citizen and lawyer.”

“All of us have dark spots on our soul, even the best of people, and most of us die having carried the shame alone and in secret. Such is the nature of many addictions, impossible to understand by those without the addiction,” Boren said.

“Steve has accepted responsibility for what he has done, is embarrassed for his friends and family and is ashamed. He will accept whatever punishment a judge deems appropriate. The good things he has done for so many are not erased; but he is forever tarnished, regardless of how the remaining court process turns out.”

Mannear’s case has been assigned to U.S. District Judge Shelly Dick.

The FBI, East Baton Rouge Parish Sheriff’s Office, and Naval Criminal Investigative Service investigated the matter.

Mannear also could be fined and ordered to pay restitution to any victims and forfeit property used in his alleged criminal activity.
