In the quiet town of Columbia, Tennessee, a deeply disturbing event unfolded on October 15, 2018, forever marking the community. On that day, 15-year-old Lia Lin Collier, a female, was found deceased in her home. The grim discovery was made by one of her adult siblings who had just returned from work. The scene that awaited was one of unimaginable horror; Lia, along with her three siblings, Kaileigh Lin, 17, Meigan Lin, 14, and Bo Li, 14, were all found dead from gunshot wounds to the head. The children, all of whom were adopted and homeschooled, were described as being part of what appeared to be an immaculate home, with no prior history of calls to the residence.

The investigation into the tragic deaths quickly pointed towards a murder-suicide. Authorities identified the perpetrator as the children's mother, Cynthia Collier. Evidence found at the scene, including a short suicide note, supported the conclusion that Cynthia had fatally shot her four children before taking her own life. Two guns were recovered from the home. The motive for this devastating act was not immediately released by investigators.

Lia was remembered as a young woman of 'unrelenting joy and exuberance.' Those who knew her described her as a loving, tender, and selfless individual who was always concerned about the well-being of others. She had a passion for baking, crafting, and sewing, and found great happiness in giving gifts. Her obituary paints a picture of a 'sweet hearted social butterfly who enjoyed good jokes and teasing.' Further details from autopsy reports later revealed the brutal nature of the crime, indicating that Cynthia Collier had fired a total of 34 rounds into her children. Kaileigh Lin was reportedly found in the bathroom with 17 gunshot wounds, while Lia Lin was discovered in her bed. The father and other family members were questioned as part of the ongoing investigation. A private memorial service was held for Lia at a later date.
