Baltimore County officials have identified three people found dead on a cabin cruiser at a marina in Bowleys Quarters. Officials say they were apparently killed by carbon monoxide poisoning.
Baltimore County police identified the victims as 34-year-old Laura Jean Gladden, of Middle River, 39-year-old John Elijah Marsh, of Dundalk, and 42-year-old Patty Mae Vento, of Plantation, Florida.
Around 1 p.m., authorities responding to reports of unconscious individuals found the trio dead inside the 30-foot cabin cruiser at the Parkside Marina.

County fire department spokeswoman Elise Armacost says carbon monoxide meters showed the level of carbon monoxide at 30 parts per million. She says levels that high always require an evacuation of the area.
Fire officials don't know what caused the gas to build up in the boat but Armacost says the problem may be related to the boat's generator. She says all the boat's ventilation hatches were completely closed.
The poisonous, odorless, colorless and tasteless gas is a byproduct produced when fuels aren't completely burned.
