Baltimore County fire officials blamed the deaths of three people found Monday afternoon on a cabin cruiser in a Bowleys Quarters marina on carbon monoxide poisoning.

The victims were two women and one man, whom fire spokeswoman Elise Armacost suspected were local residents but could not identify until family members had been notified. Authorities responded to a report from a concerned relative of one victim who went to Parkside Marina at about 1 p.m. and discovered three unconscious bodies on the floor of the boat?s cabin.
