BATH COUNTY-Sen. Creigh Deeds, the Democratic nominee for governor of Virginia in 2009, is in critical condition after being stabbed in his Bath County home early Tuesday.

His 24-year-old son Austin, nicknamed Gus, who'd been shot, didn't survive.

The 55-year-old senator was flown to the University of Virginia Medical Center after being found in his home. Authorities he was stabbed in the head and upper torso.

'(Sen. Deeds) is being treated for serious injuries,' said State Police spokeswoman Corinne Geller.

'We believe it incident occurred this morning, shortly before the 9-1-1 call came in (around 7:25 a.m.),' Geller added.

She would not speculate on whether Gus Deeds' gunshot was self inflicted; however,Geller did say officers are not looking for suspects.

On Monday afternoon, State Police said after the stabbing, Senator Deeds walked out of his home to Route 42 where he was picked up by a cousin. The two drove to the cousin's home where the 911 call was made.

Geller also said Sen. Deeds made comments to police before getting medical care.

Investigators are working to determine the sequence of events and a possible motive.

Deeds, a Democrat, has been a member of the Virginia Senate representing the 25th District that includes Charlottesville, since 2001.

A former Bath County prosecutor, Deeds was elected to the House of Delegates in 1991 and to the state Senate in 2001, in a special election after the death of Emily Couric. He ran for attorney general in 2005, but lost to Bob McDonnell, a Republican. The margin of victory was fewer than 400 votes out of nearly 2 million cast.

Deeds and McDonnell squared off again in 2009 in the race for governor after Deeds defeated Terry McAuliffe and Brian Moran in the Democratic Party race. Deeds lost badly that time.

Deeds, who drafted a constitutional amendment guaranteeing Virginians' right to hunt, has long enjoyed support from the National Rifle Association and other gun-rights advocates.

Deeds and his wife, Pam, divorced shortly after the 2009 campaign. Deeds remarried last year.
