Huntingdon State Correctional Institute

During his 10-day lockup at Huntingdon State Correctional Institute in the Keystone State, Luigi Mangione received 54 emails and 87 physical letters, along with 163 deposits into an account allowing him to buy snacks and other commissary items, correction officials said.

Officials refused to say how much money the 26-year-old was sent — or describe the contents of the letters.
