Emilie Anine Skovgaard Meng, 17, disappeared in the early hours of 10 July 2016 after a night out with friends in Slagelse, Denmark. She and her friends arrived at Korsør railway station around 4 a.m., and Meng set off to walk home alone; she never arrived, and she never appeared at a local church where she was expected to sing later that morning.
Her disappearance prompted a highly publicized search. Volunteers hung missing-person posters across the country, and hundreds of people joined the police effort. Early tips led investigators to question and release three suspects, including a 33-year-old truck driver and a 67-year-old man whose home was searched five times. After roughly four months, police said they were working from three theories: that Meng had run away, been involved in an accident, or been the victim of a crime.
On 24 December 2016 — 168 days after she went missing — Meng's body was found in a lake at Regnemarks Bakke, near Borup in Køge Municipality. Police cordoned off the site, and at a press conference the following evening announced that she had been the victim of a very serious crime. A post-mortem determined she had been strangled. A memorial service was held at Korsør Station on 26 December, attended by several hundred people, including Slagelse's mayor. Meng's funeral took place on 19 January 2017 at St. Povl's Church in Korsør, and she was buried in Korsør Church cemetery.
In June 2017, police released a technical analysis of surveillance footage from Korsør Station showing a car — assessed by an expert as most likely a Hyundai i30, 2011–2016 model — near the station at about 4:07 a.m. on the night Meng disappeared. By then investigators had interviewed roughly 650 people, filed close to 2,000 reports, and compared about 400,000 vehicles against phone records, without identifying a suspect.
The case broke open nearly seven years later. On 15 April 2023, a 13-year-old girl disappeared in Kirkerup, in Slagelse Municipality, after finishing a newspaper delivery round; she was found alive the next day at a house in Svenstrup, Korsør, where a 32-year-old marketing manager, Philip Patrick Westh, was arrested. Two other people who had also been arrested were released the same day. Westh was charged over the Kirkerup case, and police were reported to have seized a white Hyundai i30 he had sold to a family in Slovakia in 2016 — the same model sought in the original Meng investigation. On 26 April 2023, police charged Westh with Meng's murder as well as an unsolved November 2022 crime in Sorø, confirming he had been among roughly 1,450 people whose DNA police had collected in 2016, though the sample recovered at the time had been too degraded to produce a result.
A court-ordered ban on publishing Westh's name was lifted in April 2024. At trial, which began 14 May 2024 at Næstved Court House, he admitted charges related to the 13-year-old but pleaded not guilty to Meng's murder and to charges involving a 15-year-old student in Sorø. In June 2024, Westh was found guilty of Meng's murder and of abducting two other girls, and was sentenced to life imprisonment. He withdrew a planned appeal in late 2025 and, in May 2026, confessed to Meng's murder.
