Roberts, Michale, "Carbon Monoxide Lawsuit filed on behalf of the late, beautiful Lofgren family: a photo gallery", Westword [website] retrieved 2018/07/31, original source: https://www.westword.com/news/carbon-monoxide-lawsuit-filed-on-behalf-of-the-late-beautiful-lofgren-family-a-photo-gallery-5874167
As noted in the Lofgren family civil suit, parents Parker and Caroline Lofgren, along with their adorable children, Owen, ten, and Sophie, eight, traveled to Aspen to spend Thanksgiving weekend at a facility called The Lodge. That evening, the lawsuit states, snow began falling on their rental home. As snow accumulated on the roof, a sensor triggered a gas-fired boiler called the "Munchkin" to melt it.
But something went terribly wrong. At five p.m. on November 28, 2008, family friends discovered the Lofgrens' bodies -- and they were in fearful condition, according to the lawsuit:
The decedents Parker and Caroline Lofgren were found in their nightclothes on the bed. Caroline had hemorrhaged from her mouth or nose. Owen was found on the floor by his father beside a nightstand. Sophie was found on the floor by her mother with her face bloodied. Blood was also found on the bedding of one of the bunk beds in the children's guest suite.
It was later confirmed that carbon monoxide poisoning killed the Lofgrens, with evidence pointing to the Munchkin boiler. The suit alleges that the causes of the poisoning included, but were not limited to, a disconnected exhaust vent, a disconnected fresh air intake vent, a defectively designed boiler, an improperly installed HVAC system and the absence of a carbon monoxide detector. The document argues that several of these factors "were open and obvious violations of Pitkin County Code."
Really? readers take note that a disconnected exhaust flue vent connector alone would be likely to vent combustion products into the occupied space, and a disconnected fresh air intake could, if the result was inadequate combustion air, cause production of carbon monoxide in a gas boiler. Niether of those defects would, in our opinion, need to be specific problems unique to a particular heating boiler brand or model.
The tragic deaths reported by several sources including Roberts should be taken as a warning to assure that heating equipment is properly installed and that there are properly-located, tested, working carbon monoxide detectors in the building.
