Where on Lake Ontario was this? NY side or Canada? If NY, which police
department was involved?

It happened at olcott about 7 years ago. I called coast guard & they summoned
sheriff dept. Sheriff showed up an hour after I hailed coast guard.

Well, if that ever happens again and you get the same unsatisfying results,
call the state police. Sometimes you need the gestapo, not the boy scouts.

In most states the state cops are just "speeder maids". You usually get the
criminal cases from the county or the city.
