A woman was killed and a man wounded in a lakeside Maple Grove home Wednesday evening, and the couple's son was arrested.

Elizabeth J. Witt, 68, was found dead about 7:40 p.m. Wednesday in the home on the 6600 block of Eagle Lake Drive, where they found her and husband George B. Witt, 71, with severe head injuries, according to police.

A 911 emergency dispatcher told police that he "heard some kind of scuffle or fight over the phone, then the line disconnected."

Authorities began CPR on Elizabeth Witt but she soon died. George Witt was taken to a nearby hospital with life-threatening injuries.

Maple Grove Capt. Adam Lindquist said Thursday afternoon the man was in stable condition.

The suspect was taken into custody soon afterward and booked into jail, authorities said. Public records show he lives at the same address. The man has not been charged. The Star Tribune generally does not identify suspects before they are charged.
