Maryland state police investigators continued pursuing clues yesterday into the mysterious dawn shooting Monday of two Florida crew members aboard a docked commercial fishing boat in West Ocean City, but they remained mum about suspects or motive.

Investigator Paul Ford said officers interviewed several persons who worked or lived near the cluttered commercial fishing dock where the Sundance II, a 55-foot deep-sea fishing craft, was found by police at 5 a.m. Monday with two of its four crew members shot, one fatally.

"We've gotten some leads and we're trying to run them down; that's all I can tell you," said Ford.

Other police sources said both the men suffered gunshot wounds and were discovered on the top deck of the boat by the other two crew members who called police.

The man found fatally shot was identified as Norman R. Kane, 28, of Pompano Beach, Fla. The wounded crew member was identified as William T. Oosterga, also 28, of Deerfield Beach, Fla. Oosterga was rushed to Peninsula General Hospital in Salisbury where he was still listed in critical condition late yesterday.

Maryland police would not speculate about the cause of the shooting. Broward County authorities in Florida said both Kane and Oosterga had been arrested there on drug charges in recent months. Kane was charged in February with possession of cocaine, according to Deerfield Beach police. The county prosecutor's office said Oosterga served 30 days in jail for possession of small amounts of cocaine and marijuana in March.

Residents of West Ocean City, a cluster of industrial docks, seafood processing plants and marine repair shops just across Isle of Wight Bay from the resort town of Ocean City, said the Sundance II is a Florida-based boat, well known in the fishing community, that had been docked at the South Harbor Drive pier for several days before the shooting incident.

"It's a 'long-line' fishing boat for catching swordfish," said Bill Wimbrow, the owner of a West Ocean City boat repair shop. "It fishes Florida and Puerto Rico waters in the winter . . . and then comes up this way in the summer sometimes." A long-line boat, he said, is one that trolls with a line or cable several miles long with baited hooks set at intervals on the line.
