U.S. double-homicide suspect arrested at N.B. border

A man suspected of a double homicide in the United States was arrested at the border in Woodstock, N.B., Tuesday night.

Joseph Wright, 23, of Lynn, Mass., is the son of one of the two women found dead behind a school in Saugus, Mass., on Tuesday morning.

He allegedly admitted to Canadian customs authorities after he was apprehended that he had slit the throats of his mother and grandmother and then dumped their bodies behind Lynnhurst Elementary School, according to the Boston Globe.

Wright is accused of killing his mother, Donna Breau, 54, and his grandmother, Melba Trahant, 83, according to a sworn statement filed by investigators in support of an arrest warrant, the Globe reports.

Their bodies, which had stab wounds and slashed throats, were discovered about 6:45 a.m.

He's expected to face two counts of first-degree murder in Massachusetts on Thursday.

Canada Border Services Agency officers had asked Wright to go to a secondary screening area at the border, but he abruptly drove away.

RCMP were called to assist and apprehended Wright, who had abandoned his vehicle in a wooded area about four kilometres from the border.

Wright was arrested by CBSA under the Customs Act and Immigration and Refugee Protection Act for failing to report.

On Wednesday, he was handed over to U.S. authorities in Houlton, Me., and is charged with being a fugitive of justice.

He will be transported to Massachusetts.
