Posted: Updated:

TUCSON, Ariz. -- A former fourth grade teacher at one Tucson Elementary School was sentenced Monday after pleading guilty to two counts of sexual exploitation of a minor.

Joseph Chanecka, who taught at Van Buskirk Elementary, turned himself into police last July after investigators got a tip he may have child porn on his home computer.

They checked up and found 90,000 images.

Chanecka was sentenced to seven and a half years in prison.
