On a daily basis, New Hampshire’s jails and prisons send new inmate bookings to Immigration and Customs Enforcement to help the federal agency identify potential undocumented immigrants.

That’s according to a June 26 affidavit filed in a federal court case out of Hillsborough County showing a man’s illegal status was recently identified that way after he was booked at the Hillsborough County House of Corrections.

The affidavit, written by Manchester-based ICE Deportation Officer Kevin Williams, reveals, “ICE receives daily lists from the New Hampshire houses of corrections of all new ‘intakes’ — that is, all new inmates in each house of correction. ICE then runs record checks on these inmates to determine if any of them are foreign nationals that may be subject to removal from the United States.”

Several county jails have confirmed they supply ICE with daily booking lists, including Merrimack County.

“Our inmate roster is sent out to multiple agencies daily to include DHHS, law enforcement, mental health providers and ICE,”  said Kara Wyman, the assistant superintendent for the Merrimack County Jail.
