FORT WORTH -- Parents were stunned after a middle school teacher's arrest on charges of capital murder. Police believe he gunned down two people in Fort Worth early Sunday morning.

Cary Joseph Heath, 35, was arrested at Permenter Middle the very next day. The arrest occurred after school, said Cedar Hill ISD.

Police are still investigating the double murder in the 800 block of Buffalo Springs Drive. Records show Heath lives in the 900 block of Buffalo Springs.

He is currently being held at the Fort Worth jail with a $1 million bond.

His bio on the school's website has since been taken down, but it said Heath is an eighth grade science teacher who was in his first year at the middle school. Prior to that, he served 13 years in the U.S. Air Force.

The murder victims have not been identified. Police had initially detained another man for questioning in the case but he was not arrested.

Cedar Hill ISD said Monday night Heath has been placed on administrative leave. They said they notified parents via an automated phone message, but a number of parents told our crew they had not heard about the incident.

Some were concerned that a man police believe was capable of murder was around children every day.

"It's very scary. You have all the kids over there, you don't want anybody's kids to get hurt, whether its yours or anybody else's, They should be safe over there to get their education and come home," said parent Teresa Moreno.
