SANFORD, Fla. -- Authorities and volunteers are searching a central Florida lake for two boaters who disappeared over the weekend.
    
State wildlife officials say Charlie Jackson and Jason Cobb may have been ejected early Saturday from their 15-foot fishing boat, which was found later that afternoon. Volunteers in airboats and all-terrain vehicles were searching along the shore of Lake Jesup in Seminole County on Monday.
    
The Orlando Sentinel reports that authorities already used sonar and a sheriff's office helicopter equipped with heat-sensing technology to try to find the men in one of central Florida's largest lakes known for its alligator population.
