USP Coleman II is the second of the two high-security penitentiaries at the Coleman federal complex in Sumterville, Florida, completed in 2004 as an expansion built to complement USP Coleman I. Like its sister facility, it houses male inmates who need the highest level of security available in the federal system, often because they couldn't be safely managed at other high-security prisons elsewhere in the country. It has held a number of inmates who drew significant national attention, including disgraced sports doctor Larry Nassar and a man convicted in a foiled bombing plot near the U.S. Capitol. Coleman II typically holds a population in the low thousands, similar in size to its counterpart. Because it's part of a multi-facility complex, inmates are sometimes moved between Coleman II and the other Coleman units as their security classification or programming needs change over time. For families, the main thing to understand is that this is a high-security setting with correspondingly strict visitation and communication rules, distinct from the lower-security institutions sharing the same complex.
