A day at Seabrook Beach in New Hampshire turned deadly for a Massachusetts couple.

Officials say multiple swimmers got caught up in very strong currents Sunday afternoon.

CPR was performed on the two victims. Both patients, a husband and wife from Methuen, were rushed to area hospitals. 49-year-old Michael Cote was pronounced dead at a local hospital on Sunday. His 47-year-old wife, Laura died on Monday.

According to CBS Boston, lifeguards from nearby Hampton Beach arrived at the scene via boats and jet skis, to assist in the rescue. There are no lifeguards stationed at the section of Seabrook Beach where the rescues took place.

Several other people, authorities say, struggled in the strong currents and were helped by a good Samaritan as well as emergency personnel.

On Sunday, Seabrook Police issued a swim advisory, due to the strong currents in the ocean.
