Morro Bay police have discovered the cause of a loud boom Sunday night at the Dynegy Power Plant. On Monday morning, police found a device appearing to be homemade fireworks.
The device, made in part out of a Diet Coke case, was found in a parking lot owned by Dynegy, right next to the power plant. Police think this was an isolated incident. They are working with the Morro Bay Fire Department to take the device apart and analyze it for fingerprints. No one has yet been arrested.
