The U.S. Coast Guard Cutter Winslow Griesser and the 23-foot commercial fishing vessel Desakata collided Monday afternoon about four nautical miles north of Dorado, Puerto Rico, according to the Coast Guard.

The crew of the Griesser recovered two fishermen from the Desakata: Carlos Rosario, who was fatally injured, and his brother Samuel Rosario Beltrán, who was injured in the collision.

 “We sincerely mourn the passing of Carlos Rosario following the collision between a Coast Guard cutter and the fishing vessel Desakata this afternoon,” said Capt. José E. Díaz, commander of Coast Guard Sector San Juan, in a statement after the accident. “We send our most heartfelt condolences to his family, friends and loved ones, and pray they find strength during this most difficult time. A thorough investigation will be completed to determine the causal factors that led to this collision so that we can prevent this type of incident from occurring in the future.” 

Coast Guard watchstanders at Sector San Juan were notified of the incident by the cutter crew at approximately 2:19 p.m. Monday, and directed the launch of a 45-foot response boat crew from Station San Juan. The San Juan boat located the damaged fishing vessel at the scene, while the Griesser transported both of the recovered fishermen to Coast Guard Base San Juan for transfer to awaiting emergency medical services.

EMS delivered Samuel Rosario Beltrán to the Centro Medico hospital in San Juan. The remains of Carlos Rosario were transferred to Forensics Science Institute in San Juan. 

Cutter Winslow Griesser is a 154-foot Sentinel class fast response cutter homeported in San Juan, Puerto Rico. The National Transportation Safety Board (NTSB) is leading the investigation into what caused the collision.
