Police in Florida say two teenagers were found dead inside a SUV in a garage.

In a news release issued Monday, police officials said a woman found her 17-year-old son with his 14-year-old girlfriend in the family's garage, which was not attached to their apartment in St. Petersburg.

Police say they were in the boy's 2002 Mitsubishi SUV. The garage door was closed, and the vehicle was running. Investigators say it doesn't appear to be a case of suicide.

St. Petersburg emergency workers pronounced both victims dead at the scene.

The woman said her son left home Sunday afternoon to get his girlfriend. She was unaware of their return. She told police she tried calling him several times and reported them missing Sunday night.

Their names haven't been released.
