Children file lawsuit following fatal carbon-monoxide poisoning in Cambria

Three teenage children have filed a lawsuit claiming that a Navien tankless water heater caused the carbon-monoxide poisoning that killed their parents, John and Kristen Ruskey, while staying overnight at an oceanfront home in Cambria. The complaint states that the water heater and its venting system leaked carbon monoxide from an adjacent laundry room into the guest bedroom where the couple was staying.

Allegations Against the Manufacturer

The lawsuit targets Navien, Inc. and Kyung Dong Navien Co. on a products liability claim, alleging the company knew its products were potentially deadly years before the incident. According to the complaint, the water heaters have caused at least nine deaths in the United States and abroad since 2019 and led to a recall of 13,000 units in 2011. The U.S. Consumer Product Safety Commission has issued multiple recall notices regarding detached vent collars and carbon-monoxide risks.

Claims Against the Homeowners

The children also filed premises liability claims against the homeowners, Ben and Robin Korman. The complaint asserts that the residence did not have a working carbon-monoxide detector. While a combination carbon-monoxide and smoke detector was found in the room, investigators noted it was disconnected at the time.

What This Means for Ordinary People

This case highlights the hidden dangers of faulty gas-powered appliances and the critical need for functional safety devices in homes. Anyone with a tankless water heater should check for manufacturer recalls and verify that venting systems are properly installed. Homeowners and guests should also ensure that carbon-monoxide detectors are connected, operational, and tested regularly, especially ahead of colder months when heating equipment sees heavy use.

When to Consult a Lawyer

Families affected by unexpected tragedies involving defective household appliances or property hazards may benefit from speaking with a legal professional.
