Cosumnes Fire Department officials say an explosion in the back yard of an Elk Grove home occurred this afternoon as a 20-year-old engineering student was trying to build a rocket motor for a class project.

Deputy Fire Chief John Michelini said neighbors reported the explosion at 1:05 p.m. at 10318 Frank Greg Way in south Elk Grove. He said the resident told firefighters that he was building model rocket engines when one exploded.

Michelini said two additional devices were found intact, and members of the Sacramento County sheriff's explosive ordnance team and the Sacramento Fire Department’s hazardous materials team were called to the scene, along with the Elk Grove Police Department. The two devices, described as homemade solid fuel rocket motors, were destroyed by the bomb squad.

The man working on the devices was the only person at the home at the time. Michelini said the explosion broke a couple of windows on the house, but no injuries were reported

He said four neighboring homes were evacuated while authorities evaluated the scene, and residents have been allowed to return.

The man was reported cooperating with authorities, who said it will be up to the Sacramento County District Attorney’s Office to determine whether any charges are filed.
