The former stepfather of a murdered 12-year-old Vermont girl was sentenced Friday to more than 16 years in prison on child pornography charges.

U.S. District Judge Xavier Rodriguez sentenced Raymond Gagnon in San Antonio to 16 years and eight months in federal prison.

Gagnon expressed grief and remorse in accepting the sentence.

The FBI found child pornography while searching Gagnon's San Antonio home after his former stepdaughter, Brooke Bennett, disappeared in Vermont last summer.

Gagnon had been married to Brooke's mother for four years before the couple separated in 2004.

Brooke's uncle, Michael Jacques, is accused of molesting and strangling Brooke in July 2008.

Prosecutors are seeking the death penalty. Jacques pleaded not guilty last fall to a variety of charges, including kidnapping with death resulting.
