The New York City Medical Examiner's Office has closed the case of Colin Marma, a 26-year-old from Garrison, who was reported missing in February and later found dead in the Atlantic Ocean off the coast of Rockaway Beach.

Marma was reported missing by his family on Feb. 2. After extensive searches, his body was recovered on March 27.

The medical examiner's office said an investigation, including additional tests, was conducted but a definitive cause of death could not be determined.
