Authorities are searching for a man suspected of shooting two sheriff's deputies in suburban Chicago and warning the public that he should be considered "armed and extremely dangerous."

The McHenry County sheriff says investigators believe 52-year-old Scott Peters fled after opening fire with a rifle as deputies responded to a domestic dispute early Thursday morning in Holiday Hills.

Sheriff Keith Nygren (NEYE'-grin) says Peters' whereabouts are unknown, and that deputies are going door-to-door in the small village to make sure everyone is safe. The sheriff says the military veteran should be considered "armed and extremely dangerous."

Authorities say the deputies are in stable condition, and the suspect's wife and child, who were in the home, weren't injured.

Holiday Hills is about 45 miles northwest of downtown Chicago.
