Mayor Rahm Emanuel took time Friday to pay respects to a Chicago police officer who died a week ago.
Funeral services for Paul Nauden, 46, were held at House of Hope on the city's far south side.
Dozens of officers, city leaders and Chicago's new police superintendent, Garry McCarthy, were among the mourners.
Nauden, a narcotics officer, was on patrol duty when he experienced chest pains and was taken to the University of Chicago Medical Center where he later died. An autopsy determined Nauden died of a heart attack.
Nauden grew up on the city's southwest side and was a 21 year veteran of the force. He leaves behind a wife and two daughters.
