A man who killed his mother and grandmother in Lynn, Massachusetts and then tried to flee to Canada at the Woodstock, N.B. crossing has been sentenced to two consecutive life sentences.

On Monday, 25-year-old Joseph Wright III was convicted for the April 2012 slayings of 54-year-old Donna Breau and 83-year-old Melba Trahant. Wright lived in the home with his mother, one floor above his grandmother.

Prosecutors said Wright slit the women's throats and left their bodies under a tarp behind a school where they were later found by a custodian.

Wright then drove his grandmother's car from Massachusetts to northern Maine and attempted to enter New Brunswick at the Woodstock Port of Entry. Canada Border Services Agency said Wright fled the scene when officers directed him to a secondary screening area for additional questioning.

The RCMP apprehended the fugitive about 5 miles from the border in Richmond Corner, New Brunswick and he was turned over to U.S. authorities.

Wright was found guilty Monday in Salem (Mass.) Superior Court of two counts of first-degree murder with extreme atrocity or cruelty.

His attorney said Wright was likely under the influence of drugs at the time of the killings.
