A Dallas-area middle school teacher has been arrested and charged with capital murder in the killings of two men in Fort Worth.

A Fort Worth police statement says Cary Joseph Heath was arrested Monday at Permenter Middle School in Cedar Hill, where he was a first year teacher after serving 13 years in the Air Force.

Police haven't released much information on the shootings, which happened about 4 a.m. Sunday. Officers arrived to find two men dead on the driveway of a house. Officials have not formally identified the men, and a possibly motive was unclear.

The two men killed were neighbors of Heath, KXAS reported.

"From my understanding, the guy had an assault rife. From the looks of it, due to the shell casings, he unloaded the whole clip and killed two of the people who lived next door," Jordan Milner, who lives across the street from the two men, told the news station.

The Star-Telegram reported that Heath's profile stated, “I am excited to be at Permenter to provide structure and discipline for your student. My goal as an educator is to provide a quality education while focusing on success in our global marketplace.”

Bond has been set at $1 million.

No attorney is listed in jail records for the 35-year-old suspect.
