OTTAWA - Sen. Pamela Wallin is leaving the Conservative caucus, the second senator in as many days to do so amid a storm of allegations of dubious expense claims.

Wallin's travel expenses, which total more than $321,000 since September 2010, have been the subject of an external audit by Deloitte since December.

"I have been co-operating fully and willingly with the auditors," Wallin, a former CTV broadcaster, said in a brief written statement Friday evening.

CALGARY - Calgary police have charged a man in the stabbing deaths of a woman and her young son.

Thirty-five-year-old Chona Manzano and five-year-old Gabriel Manzano were found dead Thursday in a home on the northwest edge of the city.

Police said a family member was alerted to a problem and went to the home around lunch time.

He found the woman's body on the main floor of the house and the child upstairs.

Investigators soon noticed one of the family's vehicles was missing.

Zombies will be stumbling around a Saskatchewan lake this weekend, but not to worry.

The world is not ending, but people are training for it.

Jonathan Michell is one of the organizers behind the Zombie Prep Camp taking place at a camp on Katepwa Lake, about an hour northeast of Regina.

Michell says they came up with the idea because camp is fun and adults should have a chance to go, too.

Canadian astronaut Chris Hadfield says he's interested in politics but has no immediate plans to make it his next career.

In an interview with The Canadian Press, he was asked whether he might use his newfound fame as a springboard into the political arena.

"I'm as interested in politics as any Canadian, of course. That determines the fate of our country," Hadfield said Friday in an interview from Houston.

"But for me personally, right now, I have no aspirations at all."

OTTAWA - The Senate was scrambling to salvage its reputation Friday as it declared it would take a sober second look at Sen. Mike Duffy's expense paperwork — and as another embattled senator stepped down from the Conservative caucus.

Sen. Pamela Wallin, like Duffy a former CTV broadcaster, said she would recuse herself from Conservative ranks pending the outcome of a comprehensive audit of her travel expenses — more than $321,000 since September 2010.

The Criminal Code Review Board has ruled that Vince Li can go on more escorted day trips from the Selkirk Mental Health Centre where he is in custody.

SAINT JOHN, N.B. - The suspect in the slaying of New Brunswick businessman Richard Oland is his son Dennis, say search warrant documents that were executed in the investigation.

A Saint John, N.B., judge quashed on Friday a publication ban on the identities of those subject to the search warrants.

Dennis Oland's property in Rothesay, N.B., a suburb of Saint John, was searched after his father's death nearly two years ago.

In a document that was used to obtain the search warrant, a local police officer identified Dennis Oland as the suspect in the case.

OTTAWA - Canada's inflation story is fast becoming one about disinflation.

Statistics Canada reported Friday that the annual rate fell an astonishing six-tenths of a point to 0.4 per cent last month, the lowest it's been since October 2009, as gas prices plunged by six per cent — also the biggest drop since October 2009 — and many other consumer goods registered outright declines.

In the tiny town of Shawville, Que., about 18 kilometres from where Earthquakes Canada located the temblor's epicentre, residents described thinking at first there had been an accident or an explosion.
