Tampa, FL – Tampa police are investigating the deaths of a man and two family dogs, and police they say were likely the result of carbon monoxide poisoning.

Dispatchers got a call around 9:44 a.m. Monday that a man was unconscious inside of his house on East Davis Boulevard.

When paramedics arrived, the 55-year-old man and a 53-year-old woman were found inside. The man and two family dogs were pronounced dead.
