HALIFAX -- Halifax police have a man wanted for murder in the United States in custody after he was arrested for shoplifting at a local business.

A video from the Manitoba RCMP shows 28-year-old Derek Cameron Whisenand after he illegally crossed into Canada near Haskett, Man., at the end of June. On June 26, his car was found three kilometres from the Canadian border.

Whisenand made his way to Nova Scotia and was apprehended by police at a store in the Bayers Lake Business Park.

"Shortly before one o'clock, our officers were alerted to a shoplifter that was trying to escape custody in the 200 block of Chain Lake Drive," said Halifax Regional Police spokesperson Const. John MacLeod.

The man fled on foot and was followed by officers, who arrested him about 30 minutes later. When police were able to identify him, they discovered there was a Canada-wide immigration warrant for his arrest.

"The man's name was Derek Whisenand and the warrant was an immigration warrant in the U.S. for a homicide file in Texas," MacLeod said. "The man was turned over to Canada Border Services and they will facilitate his extradition to the U.S.

Whisenand is wanted as a suspect in the murder of 78-year-old Burton Duane Sanborn, whose body was found in his home in Eastland County, Texas in June.

Earlier in the summer, Manitoba RCMP warned residents that Whisenand had crossed illegally into the province and was travelling with a large dog. Halifax police confirmed Tuesday that the Nova Scotia SPCA has confiscated Whisenand's dog.

Meanwhile, the Canada Border Services Agency refuses to provide details concerning where Whisenand is being held, as well as when he will be extradited to the U.S. – privacy as the reason for not releasing those details.
