The Supreme Court of Newfoundland and Labrador has ruled that a doctor should be extradited to the United States to face murder charges.

A judge ruled Thursday that there's enough evidence to justify sending Dr. Shirley Turner to Pennsylvania to face charges in the murder of her former boyfriend, Dr. Andrew Bagby.

Bagby was shot to death in Pennsylvania with a .22-calibre handgun in November 2001.

Turner's lawyer says he'll appeal the ruling.

"The process is not over yet," said Randy Piercey. "We'll continue to fight on."

Most of the evidence against Turner is circumstantial. While a murder weapon was never found, Turner owned a .22-calibre handgun. Cellphone records also show that Turner travelled from Iowa to Pennsylvania then back again the day of the murder.

Piercey says even if Turner loses the appeal, the minister of justice would still have the final decision. He says there are special circumstances that could persuade authorities not to send Turner to the U.S.

Canada would not extradite Turner unless U.S. authorities promise that she would not face the death penalty if found guilty.

Piercey also plans to appeal on the basis that Turner has recently had a baby. He says the father was Bagby, the man Turner has been charged with murdering.
