A Carroll man accused of crafting weapons while in custody at the Carroll County jail has filed a written guilty plea to one of the felony charges levied against him. Carroll County District Court records show 30-year-old Brice Edward Shrimpton submitted his plea Thursday to a single count of possession of a weapon in a correctional facility, a class C felony. Shrimpton was indicted in March after authorities located a toothbrush that had been sharpened into a shiv in his jail cell on March 14 and a makeshift plexiglass knife hidden under his mattress on Feb. 23. At the time, Shrimpton was awaiting sentencing related to a February burglary conviction. He was sentenced to up to 10 years in prison on that class C felony charge. Shrimpton faces the possibility of an additional 10 years of incarceration for this latest charge. A plea acceptance hearing has been scheduled for Monday, May 17.
