A Plymouth man was sentenced last week in U.S. District Court to seven years in federal prison with five years supervised release after previously pleading guilty to distribution of material involving a minor engaged in sexually explicit conduct. Lawrence Tinsman, 67, was also fined $500 in restitution. Federal court records indicate Tinsman possessed a computer which contained numerous images and videos of minors engaged in sexually explicit conduct. He downloaded the images through a peer-to-peer file sharing program, according to FBI agents, and also made the images available for download by other individuals seeking child pornography.
