PHOENIX, FEB. 7 -- Acting Gov. Rose Mofford (D) spoke by telephone with impeached Gov. Evan Mecham (R) today and met with advisers to plan taking charge of the state.

Meanwhile, police in suburban Glendale said a shotgun blast was fired at Mecham's house overnight Saturday. Hours later, Mecham's car dealership was heavily vandalized in a glass-breaking spree that left 22 cars and three buildings damaged.

Police arrested the 21-year-old son of a dealership employee in connection with the vandalism and were investigating his possible connection with the shooting.

Mofford, Arizona's secretary of state, said that she talked with Mecham only briefly, and that neither of them has received official notification of Mecham's impeachment by an overwhelming House vote on Friday.

"He was most cordial," Mofford said. "I just said that I think we should meet {after they receive official notice} and he agreed."

Spokeswoman Athia Hardt said the acting governor was expected to meet with leading lawmakers soon and may address the legislature on Tuesday.

Police said Mecham apparently was home when his house was fired at. A 20-gauge shotgun was found in the vehicle of the suspect in the dealership vandalism, they said.
