20 year old gets Carbon Monoxide Poisoning from Incorrect instalation of furnace in town home rental?
Colorado 20 year old male suffers from carbon monoxide poisoning in a rented town home after a contractor worked on the furnace. Exposure to the carbon monoxide continued for 1 month resulting in hospitalization. The 20 year old man suffered a loss in color vision to his left eye, headaches 2-3 times week, memory loss, and incurred medical bills in the process. Please keep in mind that under colorado state law the property owner can not delegate there duties to maintain a safe environment for tenants to a contractor. They will still be held responsible for the actions of there employees (ie) contractor. Please decide if the owner should be held responsible for the injuries to the 20 year old? Should the contractor share that liability? how much compensation should the 20 year old get for his color vision, future medical care, loss of enjoyment, and loss of potential earning capacity?

Please put your idea of a fair settlement and what a likely verdict would be if you were on the jury?

Thanks
