They are scheduled to appear in provincial court at a later date.
When asked why the three were not named in the media release, the RNC said because the accused were not held, the information will be sworn in at provincial court in the coming days. At that point police will know the date of first court appearance and provide that information, a spokesman said.
Police interviewed more than 50 people in April last year following Leftault's death, and in June said they had a suspect, but had not made any arrests.
Diane Leftault told CBC News in June that she was told her son had died after being stabbed in the leg. Having a background in health care, she assumed he was struck in an artery — something the chief medical examiner confirmed for her later.
