Man charged in three southern Alberta stabbing deaths faces new charges

LETHBRIDGE, Alta. - A triple-murder suspect in southern Alberta is facing two new charges of sexual assault and sexual contact with a minor.

The latest charges against Austin Vielle are not related to the murder case.

Vielle appeared in Lethbridge provincial court Thursday on closed-circuit television.

He is accused of second-degree murder in the April stabbing deaths of Kyle Devine, Clarissa English and her brother Dakota.

Police allege the accused was known to all three victims and had been in their company prior to their deaths.

Vielle's next court appearance is set for July 8.
