PHOENIX -- A Phoenix charity worker convicted of sexual exploitation of a minor has been sentenced to 170 years in prison.
Maricopa County prosecutors on Wednesday announced the sentencing of 55-year-old John Landrum Jr.
He was arrested in January 2012 following an investigation by the Arizona Internet Crimes Against Children Task Force.
Police reported finding numerous images and videos depicting child pornography on Landrum's computer in his south Phoenix home.
Prosecutors say Landrum was convicted on 10 counts of sexual exploitation of a minor following a 15-day trial.
A judge imposed a prison term of 17 years on each of the counts to be served consecutively.
Prior to his arrest, Landrum worked with the Salvation Army's Project Hope, which helps the homeless in Phoenix.
