After being convicted by a jury, our client was sentenced by the federal district judge on a drug count to a doubled-mandatory minimum term of 20 years. The mandatory minimum was doubled because our client had an old predicate Massachusetts state drug conviction. On an amended habeas petition, we convinced the court that our client’s trial attorney was constitutionally ineffective in failing to adequately investigate and then move to vacate the predicate conviction before the sentencing on the federal drug count. Our client was resentenced to time served and released.
