Jamie Zimmerman, a medical doctor who provided on-air analysis for ABC News, died in a drowning accident on Monday while vacationing in Hawaii.

She was 31, according to CNN.

Zimmerman was apparently attempting to cross the Lumahai River on the Hawaiian island of Kauai when she slipped on some rocks and was swept out to sea. When lifeguards aboard jet skis located her, Zimmerman was unresponsive.

According to police, Zimmerman was alone at the time.

Zimmerman was memorialized by ABC News President James Goldston in a note to staff members on Thursday morning.

"Jamie touched so many of us across ABC News," Goldston said. "We will miss her."
