A Big Spring man will be spending even more time behind bars for making child porn.
John Alan Conroy was sentenced on Friday for producing and receiving child porn.
He's been in custody since July of last year on a similar charge.
Conroy was sentenced to just under 34 years in federal prison.
After he's out of prison, Conroy will serve a lifetime of supervised release.
Documents show Conroy lived with a woman and her two children, a boy and girl, ages 10 and eight.
Conroy spent time searching and collecting child porn before turning his interests on the eight year old girl.
Conroy remains in federal custody.
