According to the Hennepin County Sheriff's Office, she'd gone into a cabin below the deck to rest and the boat's occupants found her 10 minutes later in distress. She was taken to Hennepin County Medical Center where she was pronounced dead.

Investigators found a hole in an exhaust pipe underneath the mattress area of the lower cabin where the girl had gone to rest. Their report says animals apparently chewed through the pipe.

The Hennepin County Medical Examiner said the cause of death was carbon monoxide toxicity and determined the death was accidental.

In 2013, a 4-year-old Maple Grove girl was hospitalized after inhaling a near-lethal amount of carbon monoxide while riding in the back of an open-air boat.
