Old combat grenade isolated on a white background
A Petaluma neighborhood is back to normal after a brief bomb scare. The Sonoma County Sheriff’s Office bomb squad was called to the area around McNear Circle near Petaluma Boulevard South over the weekend when someone found a pair of explosives that appeared to be grenades in their yard. The area was placed on lockdown for about an hour before authorities determined that the devices were old grenades, but they were filled with concrete.
