ICE assists Irish Garda investigation to arrest chief suspect in Irish Detective’s murder

Acting Deputy EAD Alysa Erich and Acting Commissioner Dónall Ó Cualáin

NEW YORK — An Irish national was recently charged in Ireland following an investigation by U.S. Immigration and Customs Enforcement’s (ICE) Homeland Security Investigations (HSI) New York, HSI Attaché London and HSI Boston, working jointly with An Garda Síochána (Garda), the national police service of Ireland.

Aaron Brady, a dual citizen of Ireland and the United Kingdom, is the prime suspect in the murder of Adrian Donohoe, a detective working for the An Garda Síochána. Detective Donohoe was fatally shot in the line of duty in January 2013 by an armed gang of five people during a robbery on a credit union. He was the first Garda officer to be shot dead in the line of duty since 1996.

The investigation revealed that Brady was living in New York, and entered the country under the Visa Waiver Program but failed to leave upon expiration of the waiver, making him amenable for arrest and removal from the United States for immigration violations.

“The United States will not be a safe haven for cop killers. When it comes to cop killers, there are no boundaries between us,” said Alysa D. Erichs, acting deputy executive associate director of HSI. “The Garda is remaining true to their promise to the Donohoe family and to the Irish people. It is an honor for HSI to have worked alongside our Garda partners to investigate, locate, arrest and deport Aaron Brady to Ireland.”

This past May, HSI New York, with assistance from ICE’s Enforcement and Removal Operations (ERO) in New York, were able to arrest Brady by citing an expired visa. He remained in ERO custody until he was removed from the United States, being escorted to Dublin and arrested by Garda Detectives upon arrival.

HSI’s International Operations Division is the Department of Homeland Security’s largest investigative presence overseas. Division personnel serve as liaisons to governments and law enforcement agencies across the globe and work side-by-side with foreign law enforcement on HSI investigations overseas. The division’s attachés have a variety of duties, including relationship building and providing assistance on active investigations and repatriation efforts.
