Gagnon told investigators that when he heard Bennett was missing, he flew from San Antonio to Burlington by way of Cullman, Ala., where he owned a home, according to the affidavit.
While in Cullman, Gagnon told authorities, he tried to access Bennett's MySpace page from a local library. After seeing Gagnon on national news, a former co-worker of Gagnon's in Cullman tipped authorities off to the fact that Gagnon owned a home there.
Authorities did a public records search and found that Gagnon did own the home along with a woman, according to the affidavit, and that he obtained an Alabama driver's license in 2006.
Federal authorities seized computers and a disk from Gagnon's Alabama home that contained child











, according to the affidavit. Gagnon admitted the computers were his, and the images were found in a file linked to the username "Ray," investigators said.
