John Kacavas


New Hampshire U.S. Attorney John Kacavas is leaving the post he's held for six years to become chief legal officer and general counsel for Dartmouth-Hitchcock health systems.

A Dartmouth-Hitchcock spokesman says Kacavas will join the health network April 20. His resignation as U.S. Attorney — announced Thursday — is effective April 17.

Hospital officials say he will oversee government relations, risk management and claims management.

Kacavas was nominated by President Barack Obama and sworn in as U.S. Attorney in August 2009.

New Hampshire is one of seven court districts where a powerful Mexican drug kingpin faces indictment. Joaquin “El Chapo” Guzman, the alleged leader of the Sinaloa cartel, was arrested last weekend in Mexico on charges of drug trafficking.

In September 2012, New Hampshire prosecutors announced the arrest of four other high ranking members of the Sinaloa cartel—including a cousin of Guzman—after an international investigation involving FBI undercover agents and the Boston Police Department.

The U.S. Attorney’s office today announced the first criminal charges in connection with the Hepatitis C outbreak at Exeter Hospital.
