Charles Brennan, also reported as Charlie or Charley Brennan, was 58 when he disappeared from Kachemak Bay, Alaska, on February 13, 1973. He was described as a Caucasian male, black hair, brown eyes, 5 feet 9 inches and about 130 pounds. The case number with the Alaska State Troopers is D73001139.

According to reports, Brennan fell from a tanker ladder into the icy waters of the bay. An immediate search was mounted by responders in the Kenai Peninsula Borough, but the bay’s treacherous conditions and the severe cold hampered efforts and no trace of him was found. The investigation was opened the day of the incident and remained active for a time before being scaled back as no new leads emerged.

What is remembered about Brennan’s work or presence in Kachemak Bay that day, or anyone who might have seen him near the tanker, could be crucial — anyone with information is invited to come forward.
