Initial search The search for Melanie began on the afternoon of Sunday, 29 September 1996 at around 14:30–15:00. New Liskeard police dispatched officers to the Ethier residence and began a search of the area around the Armstrong Street bridge and along the banks of the Wabi River within hours of her being reported missing. Deverell later said that he remained on the case up until the day of his retirement, 31 December 2002; Thib continued working on the case until he was attached to the OPP in 2007. According to the witness, she and her husband were driving across the bridge when both spotted a teenaged black girl walking south on the eastern sidewalk. In a 2021 interview, this witness (known to the public only as "Denise") disclosed that at around 01:45 on 29 September 1996 she was doing schoolwork in her room when she heard a girl screaming outside. Although she initially ignored the outburst, she heard more screaming about 45 seconds later and became frightened. After checking that her front door was locked, the witness snuck to her
bay window and saw three silhouettes of people running down the street towards Pine Avenue, but no vehicles or headlights. Her husband, who was also home at the time, did not witness the event as he was asleep. In 2020, the OPP declassified parts of Ethier's female friend's account of the evening, in which she described being spooked by a vehicle after leaving the Pine Avenue residence. Remaining anonymous, this friend has only ever spoken to the media about her experience twice and has since moved overseas. The release of
The Next Call, a
podcast about Ethier's case from the creator of
Someone Knows Something, led to another witness coming forward in 2021. According to police, the anonymous male witness was unknown to investigators before getting in touch after hearing the podcast. The tip led police to Larocque Field in North Cobalt, roughly 10 km from Ethier's last known location, where OPP officers and the Northeast Emergency Response Team surveyed the site with the assistance of search dogs and drones on 12–14 October 2021. The heavily forested terrain made looking for evidence difficult, and police suggested they would have to schedule additional days to continue searching the area.
Current status The police investigation into Ethier's disappearance has remained active since 1996. and is led by senior officer Detective Inspector Rob Matthews The province of Ontario currently offers a $50,000 reward for information that leads to an arrest or conviction for those responsible for Ethier's disappearance. All of the OPP's information about the case has been uploaded to Powercase, a newly implemented major case management system which alerts detectives to similar details in other investigations and could tie Ethier's disappearance into a wider crime spree. Tips generated by this system have led to several digs in the Temiskaming area which have failed to uncover Ethier's remains. In 2010, the OPP stated having received over 700 tips from 500 witnesses relevant to the Ethier case, as well as having over 300 persons of interest; in 2020, they were receiving on average 2–3 tips per month about the case. The OPP has also gone on record to say they follow up on tips offered to them by
psychics, Crick suspected Goulet was drawing unwanted attention to their family and that he had informed the police of their involvement in Gauthier's murder. Goulet went missing in New Liskeard on 6 or 8 November in what appeared at the time to be another teen vanishing. Goulet's body was found in a
Hilliardton gravel pit in April 1998, and was ultimately determined to have been stabbed by either Lafreniere or Crick. The surviving brother and Crick were arrested for the murder of Gauthier in December 1996. No link was ever formally established between the Gauthier murders and Ethier's disappearance. Investigators - including OPP Detective Constable Bill Deverell, who worked both cases; then-New Liskeard Police Chief Doug Jelly; and OPP Detective Inspector Rob Matthews, senior officer on the case as of 2021 - have denied any connection. Andre has denied any memory of where they had gone that weekend. Joel has said he was at a large house party in New Liskeard that weekend, and if they had attended a motocross competition it would have only been a day trip. Martel estimated the marks were about one or two days old, as they were only just starting to scab, and believed they were caused by nail scratches. Neither of Léveillé's children believe they ever witnessed him play fight with Ethier. Léveillé had a long history of making sexual advances against minors, though not everyone in his life was aware of the extent of this behaviour. His partner was aware of at least a few occasions on which he had made advances towards his daughter's friends, She had also spoken to police before the incident, providing information on the activities of a group of three local boys. Sarah, who lived on Pine Avenue at the time, was not made aware of the Ethier disappearance until Monday 30 September. At this point, Sarah (who also went by the name "Sierra") began to refer to herself as "Melanie" and dress in clothes similar to those worn by Ethier on the night of her disappearance. Days after the incident, Sarah told several people that she was Ethier at a
bowling alley in Haileybury. Sarah moved to North Bay sometime after 1998, and appears in her school yearbooks in 1997 and 1998, despite a rumour which alleged she left town weeks after the disappearance. She then moved to
Vancouver,
British Columbia. Aside from a
voicemail left for her mother in February 2020, she has cut off all contact with her friends and family; her current whereabouts and status are unknown. Peers who attended school in the area at the same time as Ethier have doubted someone would be targeted over a debt, as the illegal drugs circulating at the time would not have been expensive enough to justify murdering someone who could not afford to pay back what they owed. said in a 2020 interview that he doubts one popular theory which suggests Ethier was killed by hunters from the
United States. At the time of Ethier's disappearance, the only
hunting seasons that would have been open would be for
small game and
bear, and in the 1990s most
bear hunting took place in the spring rather than the fall months. The small game season rarely draws anyone to the community, and
big game hunters would be required to stay with a licensed outfitter or lodge. Of particular interest to the case is the suspicious vehicle encountered by the two girls who were with Ethier on the day she disappeared. Samya Benchabi, who had briefly walked with the group on the afternoon of 28 September 1996, left them and returned home after sunset, either at around 19:00 or 22:00.
Paul Alan Hachey was a repeat violent offender who was ultimately convicted of three sexual assaults which took place in
Edmonton and two murders which took place in Ontario. Hachey murdered 46-year-old
Larry Arnold on 14 October 1994 and hid Arnold's body in a ravine in
Rosedale, Toronto, where it remained hidden until 19 November nearly five weeks later; and 20-year-old
Sarah Whitehead on 7 August 1997 while she was walking home from the mall along a footpath in North Bay. Hachey was arrested in
Calgary in December 1997 for another
sexual assault. Police in Hachey's hometown of
Sturgeon Falls, Ontario made the connection between him and the murder of Sarah Whitehead using DNA retrieved from a cigarette butt at the crime scene in Calgary to tie Hachey to the crime as well as the assaults in Edmonton; he also confessed to the murder of Larry Arnold while in police custody. Although he was active in the area, his
modus operandi (or "MO") does not match the details of the Ethier disappearance and the OPP do not consider him a suspect.
Michael Wayne McGray was a serial killer who was active and transient at the time of Ethier's disappearance. Between 1985 and 1998, McGray killed at least six girls between the ages of 7 and 18 years old, and has since claimed to have been responsible for eleven more which have yet to be linked to him. McGray's confirmed crimes took place in
Dartmouth,
Moncton,
Montreal,
Saint John, and
Weymouth; but he claims that his yet-undiscovered crimes occurred in more distant locales including Calgary,
Seattle, and Vancouver. McGray was arrested on 1 March 1998. ==Public reaction==
