Disappearance of Adam, Trevor, and Mitchell O'Brien

Adam, Trevor, and Mitchell O'Brien are missing brothers from Torbay, Newfoundland and Labrador, Canada who were allegedly abducted by their father Gary O'Brien on November 9, 1996. Their kidnapping made both national and international headlines. Gary O'Brien is wanted by Interpol for their abduction. Although various tips have come in from both Canada and the United States and a $50,000 reward has been offered, police have never been able to locate the O'Brien brothers or their father. Disappearance: On November 9, 1996, Adam, Trevor, and Mitchell O'Brien went to visit their father and non-custodial parent, Gary O'Brien, at his home in Torbay, Newfoundland and Labrador, Canada. At 8:30pm that night, Gary called Diana Boland, his ex-wife and the boys' mother and custodial parent, and told her that he was not going to return the boys to her and had rigged his house so that it would explode if anyone entered it. When Diana asked to speak to the boys, Gary told her "later" and hung up. Diana's sister, who was with Diana at the time, immediately called the police. Investigation: When police first arrived at Gary's house, they discovered that Gary had set up a makeshift bomb using two 400-pound propane tanks that would have exploded and destroyed both his home and the surrounding houses if anyone had tried to get inside. Diana believes that this was done in order to create a diversion. Gary has a history of violence, suicidal tendencies, and psychiatric problems, and is described by Diana as "introverted" and "resourceful". In October 1997, almost a year after the disappearance, the engine assembly of Gary's car, a 1989 Ford Tempo, was discovered in the ocean near Flatrock, approximately ten kilometres from where the boys disappeared. No bodies were recovered from that location. Diana suspects that Gary dumped the engine of his car over the cliffs and into the ocean in order to deliberately mislead police. The following year, police in Thunder Bay, Ontario received an anonymous tip from a woman who stated that she'd recognized pictures of the brothers. The woman said that she'd babysat for them, and knew the nicknames of one of the boys. Police attempted to locate the woman until 1999, but were unsuccessful. Although Gary's sister suspects that her brother and her nephews are dead, Diana firmly believes that her sons are still alive, stating that Gary may have taken them to a religious commune and raised them in an environment with no access to technology or the outside world. She believes that being cut off from the outside world may have allowed Gary to brainwash Adam, Trevor, and Mitchell, which could be why they have never tried to contact her. In order to aid the search for the O'Brien brothers, the National Centre for Missing and Exploited Children has created multiple age-progressed photos of the boys over the past two decades, with the most recent ones having been released in early 2017. The case remains open, with tips coming in as recently as December 2016, twenty years on from the disappearance.
