MONROE - A former Monroe man's trial for sexual assault charges continued through its second day Thursday as the prosecution and defense called into question memories, the meaning of slang and the effectiveness of wall insulation. Derek J. Larosh, 29, of Rock Springs, appeared with his attorney, William Ginsberg, on two Class C felony counts of second degree sexual assault of an unconscious victim and through the use of force, before a jury of 12. Assistant District Attorney Laura Kohl, appearing for the prosecution, opened the day by calling a former Monroe Police officer, Jacob Teasdale, as a witness.
