When investigating a murder case, both detectives and prosecutors seek out the motive of the crime. Loved ones of murder victims often seek out the motive as well; in hopes for answers about what happened to someone they love. Identifying the motive of a murder not only may help in finding a victim's killer, but it also helps the prosecution build their case against the killer. However, there are cases in which a murderer was convicted without a motive ever being revealed. Although these cases are considered solved, they often leave victim's loved ones with more questions than answers. Below is a list of five such cases, in which the murderer is behind bars but the motive behind their crime remains unknown.
The Murder of Grant Nelson
Hours before they met, Mackenzie was in her hometown in California, visiting her family. She then took a flight that landed in Salt Lake during the early morning hours of June 17th. Instead of going home, Mackenzie took a Lyft to Hatch Park, where she met Ajayi for the first time. Ajayi took Mackenzie back to his home, where he ultimately attacked her. Ajayi reportedly bound Mackenzie's arms behind her back before strangling her and beating her to death. Mackenzie's family members reported her missing 3 days later.
The Murder of Brittney Gargol

A few days later, two teenagers named Kam McLeod and Bryer Schmegelsky vanished while they were believed to be travelling to the Yukon territory. The car the two were traveling in was found completely burned out on July 19th, 2019, just days after Chynna and Lucas were found. The body of a 64 year-old man named Leonard Dyck was also found nearby. Due to the close proximity of the crime scenes, police initially feared that Kam and Bryer fell victim to the same assailant as Chynna, Lucas, and Leonard. However, by July 22nd, police announced that Kam and Bryer were now considered suspects in the couple's murder and Leonard's murder.
