MONCTON, N.B. - A young New Brunswick woman who spent two-and-a-half-months as a fugitive on charges of first-degree murder and arson has been ordered to undergo a 30-day psychiatric assessment.

Marissa Shephard was arrested March 1, under a Canada-wide warrant, outside a hotel in Moncton.

The 20-year-old is charged in the Dec. 17 killing of 18-year-old Baylee Wylie, whose body was found in a burned-out triplex.

Days after the Moncton blaze, 18-year-old Devin Morningstar was charged with first-degree murder and arson.

Tyler Noel, 18, was arrested on a Canada-wide warrant Jan. 9, in Petitcodiac, N.B., and has also been charged with first-degree murder and arson.

Shephard's next court appearance is set for April 15.
