Murders of Nathan O'Brien, Kathryn Liknes and Alvin Liknes

The murders of Nathan O'Brien, Kathryn Liknes and Alvin Liknes occurred on June 29, 2014. Five-year-old Nathan O'Brien and his grandparents, Kathryn and Alvin Liknes, disappeared from the grandparents' Calgary, Alberta home after what police called a "violent incident." An amber alert was issued. This alert was lifted on July 14, 2014 after the arrest of a person in relation to the disappearance. Later on July 14, 2014, police state that they believe O'Brien and the Likneses were murdered, but they did not recover their bodies. Douglas Garland was charged with two counts of first degree murder in the deaths of the Likneses and a second-degree murder charge for killing O'Brien. The second degree charge for Nathan O'Brien was upgraded by the court to a first degree charge in May 2015. The initial disappearance led to a large outcry of support from the local community, with the disappearance prompting the longest amber alert in Canadian history as well as one of the most intensive ground searches in Calgary's history. The investigation involved multiple agencies including the Calgary Police Service, RCMP, Canada Border Services Agency, and Crime Stoppers.

Background
Douglas Garland was the brother-in-law of Alvin's son Allen. Prior to the murders he had been convicted for running a meth lab on the rural property he lived on with his parents, and had used the stolen identity of a teenager who died in a car crash in Cardston to evade the law throughout the 1990's. Garland had worked with the two after Alvin Liknes hired him to do wiring for a pump that Alvin and Allen were working on. Alvin was an inventor and had patented several designs since the 1970's. Garland had slightly altered the patent they had been working on and believed that he should have been included as one of the inventors, but Liknes disagreed. This, along with Garland being let go in 2007 caused him to develop a grudge against Alvin. When he learned that Alvin was planning on moving away he decided to act on his grudge. Police later found that Garland had searched up incriminating things such as "how to kill without emotion", "force needed for concussion" and "most painful torture". On the day of the murder, 5 year old Nathan O'Brien chose to see his grandparents with his mom over a visit to the zoo. His grandparents, Kathryn and Alvin Liknes had bought a house in Edmonton and were hosting an estate sale on the day. Afterwards, Nathan asked if he could sleep-over at his grandparents to which his mother agreed. Initially his mother and one year old brother also stayed, but after the one year old woke up during the night, his mother decided to drive him home leaving Nathan asleep with his grandparents.

Murder
Much of the details of the murder remain unknown as Garland has remained silent on the murders since his incarceration. Some time between Nathan's mother leaving the house and her returning, Garland used a drill to access the house through a sidedoor and then disabled their router. He then attacked the three and beat them until they were incapacitated and bloody with Alvin sleeping in the Master bedroom and Kathryn and Nathan sleeping in the front bedroom. Evidence was presented in court showing that Garland attempted to clean the floor of blood using a mop before dragging the victims to his pickup truck where he drove them to his rural property. There he murdered them, likely after extended torture. DNA evidence was found on multiple pieces of evidence including a hacksaw, meat hooks, and the shoes Garland was wearing when he was first arrested that matched to those of all three victims. The theory presented by the crown is that Garland then burned the bodies near his shed to dispose of them.

Investigation
The next day at 10 AM, his mother, Jennifer called Kathryn who didn't pick up, and then went to their house. Upon entering she discovered the three missing, as well as the house covered in blood. After calling authorities, an Amber alert was issued for Nathan at 5:15 PM. Later that day police announced that evidence in the house suggested that their disappearances were suspicious. On July 1st, aerial imagery taken from a plane flown by Peregrine Aerial Surveys for the city of Airdrie showed two adults believed to be Alvin and Kathryn Liknes lying face down in the grass and a small body lying next to them near an outbuilding on Garland's farm. When the farm was flown over again the next day, the bodies were gone. On July 4th police asked for help in identifying a green pickup truck seen on multiple CCTV cameras in the area. After seeing this, Alvin's son Allen and his wife told authorities that the green pickup matched the green Ford F150 driven by Douglas Garland, leading him to become one of three major suspects in the case. On July 5th, the police organised a ground search of the area around the Likneses house, one of the largest in Calgary history. That same day the RCMP executed a search of the Airdrie property belonging to Garland and his parents.

During the initial search of the property, a green pickup truck matching the one seen in CCTV footage was found and seized. Douglas Garland was taken in for questioning, and after being released was charged with the identity theft from the 90s, allowing him to stay in police custody until July 11th when he was granted bail under the condition that he would not return to the rural property. The police search of the Garland property lasted from July 5th to July 20th, and the investigation at the Liknes home ended on July 13th. From here police collected upwards of 1,400 pieces of evidence in what was called Operation Amber, the largest number of evidence ever collected for a court case in Calgary history. Evidence collected from Garland's farm included a Tyvek suit, face masks, boots, books about disposing of bodies, whips, lockpicking devices, chemical gloves, over fourteen pairs of handcuffs, dental anaesthetic, and an assortment of knives, tasers and other weapons. 8 pairs of women's shoes, 2 blonde women's wigs and an adult diaper were also found in the basement of the house; photos of adults in diapers were also found on his hard drive which was found hidden in the rafters. A search of the area around the sheds found three blood stains in the grass as well as burned material in the nearby firepit. Evidence found in the firepit included 17 teeth, 2 of which were thought to belong to a child, bone fragments, pieces of burnt flesh, jewellery, and buttons.

Arrest
On July 14th Douglas Garland drove to his rural Airdrie property in a rental car. Two police were sent to pull him over, but when they reached the car it was parked outside the property. Due to the uneven terrain, police approached on foot, using assistance from a HAWCS helicopter to locate Garland in a thicket before arresting him at 1:25 AM.

Trial
The murder trial for Garland began on January 16, 2017. The trial drew to a close on February 16, 2017, and it took the jurors just over nine hours to reach a verdict of guilty on all three counts of first degree murder.

The following morning, Garland was sentenced, with only the minimum sentence being determined, as first degree murder carries an automatic life sentence. After 10 of the 12 jurors recommended that Garland receive consecutive minimum sentences, Judge David Gates ordered Garland be required to serve 75 years before being eligible for parole. As Garland would have to live to 129 years of age to finish the term, this means he will, effectively, be incarcerated for the rest of his life. Throughout the trial, Garland never showed any remorse or emotion. Hours after being sentenced, Garland was sent to the Calgary Remand Centre located in the city's Northwest where he was physically assaulted by multiple inmates. EMS said the victim of the assault was transported to hospital in stable, non-life-threatening condition with soft tissue injuries.

Reactions
Upon the announcement of their disappearance, Cenovus Energy, the company that the parents of Nathan worked at willed to finance a ransom for the family if one was demanded. Hundreds of people volunteered to search for Nathan in the days following the disappearance. On July 15th after the announcement of Garland's being charged with the murders, hundreds of Calgarians released green balloons in tribute of the victims. A Green Ribbon campaign was also started by a neighbour of Alvin and Kathryn Liknes. On July 19th a silent auction fundraiser was held for Nathan's family. On July 23rd a vigil was held outside the Alberta Legislature Building in Edmonton. A private memorial by the family was attended by over 200 people. The parents of Nathan O'Brien started the Nathan O'Brien Children's Foundation, which aim to help disadvantaged children. In 2015, a fundraiser game featuring the Calgary Hitmen was held at the Scotiabank Saddledome in Downtown Calgary in Nathan's honour.
