Jerry Walker Jr. pleaded guilty on Tuesday to six tampering charges in connection with a series of letters he wrote in the days following a 1998 dormitory fire at Murray State University that killed a fellow student and injured five others. Mr. Walker had been tried twice for his role in the incident, but a 2001 trial ended in a hung jury and another jury acquitted him in July. In exchange for his plea, he will serve no jail time but will help care for a memorial for Michael H. Minger, the student who died in the fire.
