The capital murder trial of three 16-year-old girls from Montgomery, Alabama this week revealed the grisly details of the killing of 17-year-old Lesley Luna Pantaleon, who had gone missing in summer before her body was found on July 4.

On Wednesday, Ta’Niya Merriweather, Erin Taylor, and Tyeshia Whisenant recounted in the courtroom how they savagely beat and stabbed to death Pantaleon before dumping her body in a creek to drown. The three said they immediately went to McDonald’s to enjoy some smoothies after killing the victim.

The three suspects said they committed the crime following a feud with Pantaleon over her missing gun. According to them, Pantaleon’s gun went missing in spring. The victim allegedly “put a hit” on the home where her gun had ended up.

On June 24, Pantaleon arrived at the house to retrieve her gun but got into a fight with Whisenant. She then piled into her 2006 Blue Chevy Trailblazer with the three suspects and another juvenile boy.

As Pantaleon and Whisenant’s altercation continued, Taylor pulled the car over the woods so she, Merriweather and Whisenant could beat the victim with a metal pole taken from a gate. They also stabbed her and left her there for dead.

When they returned home, however, they decided to go back to the scene of the crime to bear witness to Pantaleon’s murdered body in the woods. Whisetnant discovered that her toes were still moving so she told her two accomplices that their victim needed to be taken care of. Ultimately, they put her body in the car and drove to a creek to dump her there.

The suspects revealed that Lesley Pantaleon’s last words were, “Just take me home, you can have my truck.” However, the lawyers representing Merriweather, Whisenant, and Taylor said the girls could not be charged with capital murder since robbery was not a motive in the killing.

Capital murder only occurs when someone commits a homicide while in the process of committing another felony, such as robbery, rape, or kidnapping.

Merriweather, Taylor, and Whisenant are being tried as adults.
