MILWAUKEE (WKOW) — Two people were found dead in a home in suburban Milwaukee from an apparent carbon monoxide leak.

A family member first made the heartbreaking discovery at the home in Greenfield and called 911.

When first responders got there, they found two men, a father and son, unresponsive.

They immediately noticed the leak was coming from a furnace in the basement.

Officials are now urging you to make sure you have a working carbon monoxide detector.

Carbon monoxide detectors are required in Wisconsin. They’re easy to install and are a strong defense against the colorless, odorless, poisonous gas.
