On 16 October 2004, Edith McAlinden — described as a convicted thief, prostitute, and homeless drifter — was released from prison after serving a nine-month sentence for a serious assault. She went to a top-floor flat on Dixon Avenue in Crosshill, Glasgow, where her boyfriend David Gillespie, 42, lived alongside fellow tenant Anthony Coyle, 71, and landlord Ian Mitchell, 67, whom McAlinden referred to as "Pops."
During a drinking session, an argument broke out between McAlinden and Gillespie. McAlinden stabbed Gillespie repeatedly in the thighs, severing a femoral vein and causing him to bleed to death. She then telephoned her 17-year-old son, John McAlinden, for help. John arrived by taxi with his 16-year-old friend, Jamie Gray; McAlinden persuaded Mitchell to pay the taxi fare, with Mitchell believing the pair had come to help Gillespie.
When John McAlinden realised Mitchell had witnessed the killing, he fatally stabbed Mitchell and repeatedly kicked his head, causing heavy bleeding to the brain. Anthony Coyle attempted to escape by locking himself in his bedroom, but John and Jamie drilled out the door locks to force entry. Jamie Gray then chased Coyle and beat him to death with a golf club.
Around two hours later, at approximately 3:00, McAlinden went to a neighbour, James Sweeney, and asked him to check on the flat, claiming something had happened. Sweeney went to investigate and, upon seeing the blood-covered hallway, called emergency services. Local reporting on the extensive bloodstaining led to the nickname "The House of Blood."
Police and paramedics arriving at the scene found McAlinden alone with Gillespie's body. She was formally charged the next day, 18 October, at Glasgow Sheriff Court. Investigators initially speculated that more than one strong attacker had been involved, given the scale of blood found at the flat.
In May 2005, Edith McAlinden, John McAlinden, and Jamie Gray appeared at Glasgow High Court, initially denying the murders of Mitchell, Coyle, and Gillespie. The prosecution, led by Sean Murphy QC, described victims being beaten with knives, metal files, a belt, and pieces of wood, struck with a bottle, punched, stabbed, stamped on the head, and doused with boiling water. During the trial, all three defendants changed their pleas: John McAlinden admitted killing Mitchell, Jamie Gray admitted killing Coyle, and Edith McAlinden admitted killing Gillespie.
On 29 June 2005, Edith McAlinden was sentenced to life imprisonment with a minimum tariff of 13 years. John McAlinden and Jamie Gray each received a minimum tariff of 12 years. John McAlinden was released in 2016 but was reimprisoned in 2018 for breaching his licence conditions.
