Former Subway spokesperson Jared Fogle was sentenced Thursday to more than 15 years in federal prison, after pleading guilty to child pornography and sex crime charges.

Fogle agreed in August to plead guilty to one count each of travelling to engage in illicit sexual conduct with a minor and distribution and receipt of child pornography. The charges followed a July raid on his suburban Indianapolis home. The resulting criminal case destroyed his career as the public face of the nation’s largest sandwich restaurant chain.

Prosecutors sought a 12 1/2-year sentence, while Fogle’s attorneys asked for five years. Judge Tanya Pratt cited the serious nature of Fogle’s offenses in a sentence that went beyond the prosecution’s recommendations and said Fogle will have a lifetime of supervision after his release.

Before the 38-year-old was sentenced Thursday, his defense called forensic psychiatrist Dr. John Bradford, who has researched pedophilia and said he evaluated Fogle. Bradford, who addressed the court by phone, said Fogle’s “hypersexuality” was heightened by the extreme weight loss he experienced in college. Fogle was hired by Subway 15 years ago after he credited the sandwiches and daily walks to a franchise of the chain for helping him lose more than 200 pounds in a year.

Bradford said Fogle suffered from “mild pedophilia,” CBS affiliate WTTV reports, which the prosecution argued is not an accepted diagnosis in the scientific community.

The prosecution noted that Fogle owned child pornography that featured children as young as six years old.
