A New York State Police investigator from the Hudson Valley lost his long battle with a 9/11 related cancer.

On Thursday, New York State Police Superintendent Keith M. Corlett announced the passing of New York State Police investigator Ryan D. Fortini.

Investigator Fortini died on Jan. 1, from cancer stemming from his assignment to the World Trade Center site, following the terrorist attacks on Sept. 11, 2001, police say.

Following the events of 9/11, Fortini was assigned to aid with the search and recovery efforts in New York City, as part of the New York State Police detail, according to the New York State Police.

Investigator Fortini retired from the New York State Police after 16 years of service on July 15, 2015, because of his worsening illness, officials say. He was assigned to Troop K and then, Community Narcotics Enforcement Team in the Hudson Valley, during his years of service. According to the Dutchess County Law Enforcement Academy, Ryan served many years in Dutchess County.

Fortini is survived by his fiance, parents, brother and sister.
