USA: First Female Cop Was Irish

From Irish Central:

A retired federal agent's research has uncovered the records which show that the United States first female cop was an Irish woman.

While researching the history of Chicago law enforcement, Rick Barrett, a former Drug Enforcement Administration agent and amateur historian, discovered records of Sergeant Marie Owen, the first female cop in the United States and an Irish-born woman.

Barrett spent over three years researching Owens. He spend his time travelling all over the city befriending archivist pulling in favors with pension records, civil service documents and cemetery plot listings. Eventually it paid off.
