DENVER (CBS4) – Firefighters found two dead people in north Denver on Thursday after receiving a call from someone complaining of chest pains.

Firefighters found one body when they arrived but couldn’t continue searching the location because dogs on the property posed a hazard, the Denver Fire Department said.
