LAKE CITY, Fla. (AP) — Authorities say two men died in a north Florida home from an apparent gas leak.

Lake City police say a Jacksonville woman called them Saturday night, concerned that she hadn't heard from her husband since noon. Officers checked the home but didn't get a response.

Rescue workers responded, forced entry into the home and found 74-year-old Willie Saulsby Smith and 48-year-old John Thomas Rawls. They were both declared dead.

The Gainesville Sun reports that rescuers detected high levels of carbon monoxide inside the home.

It wasn't immediately clear what caused the gas leak.
