Rescue workers planned to continue searching waters near Gibson Island in Anne Arundel County on Wednesday for a missing man who was tossed from a boat in the area during a squall Monday, according to a Maryland Department of Natural Resources Police spokesman.

The man, identified as Jason Wesley Ryman, 27, of the Philadelphia area, was on a sailboat with three others when the squall caused the boat to tip, said Sgt. Brian Albert, the spokesman.

Ryman and his girlfriend were both thrown from the boat, Albert said. The woman was rescued, Albert said.

Emergency responders first entered the area after a call for help about 1 p.m. Monday, and searched for Ryman until dark. They resumed their search Tuesday morning, using side scan sonar and divers, and again worked until dark, Albert said.

Rescue workers were scheduled to again begin searching the area on Wednesday morning, Albert said.
