Parents in Greenwich are expressing concerns tonight after police reportedly found child pornography in the home of a now-deceased local music teacher. Police say Eastern Middle School teacher Steve Allen allegedly killed himself last month, and that they discovered the pornographic materials while searching through his Cos Cob apartment. Some parents say they are shocked by the accusations. Police say the images in Allen's apartment were of children from foreign countries which were taken off the Internet. FBI officials are working with the school district and say the investigation may take several weeks.FBI reportedly investigating Greenwich sex case
