What began as a typical teenage sleepover turned tragic in Missouri this month, as a 16-year-old girl was fatally shot in the throat by a 21-year-old woman while styling her friend’s hair at a vanity, prosecutor’s reports indicate.

Bailey Lewis, from Lenexa, faces charges of second-degree felony murder for the death of Traelynn Sibley, a Grandview High School student ready to begin her junior year, before she was fatally shot on August 9 at a residence on the 3600 block of Norton Avenue, according to the Jackson County Prosecutor’s Office.

The shooting purportedly occurred as Lewis drove by the home, aiming at someone inside with whom she had a prior dispute. Allegedly, Lewis had conflicts with this individual after she reportedly allowed them to get “attacked” at a gas station months prior.

“The pattern of bullet casings suggested that the shooter(s) were moving southbound during the incident,” noted Kansas City Police detective David Adair in Lewis’ probable cause affidavit. “Both the house and a red Mazda parked in the driveway sustained multiple gunshot damages. The building displayed signs of gunfire damage both inside and out, and a significant trail of apparent blood was observed leading from the living room to a bathroom area.”

Prosecutors report that Traelynn was visiting for an overnight stay with a friend when Lewis allegedly arrived and opened fire while the girls were working on their hair. Numerous witnesses inside the residence provided consistent accounts of the event, as stated in the affidavit.

“They described a normal night with two of the females fixing each other’s hair at a vanity near the front door of the structure, one female was in back bedroom while two adult males were playing video games in the living room,” the affidavit says.

“A toddler was also present in the home,” the document adds. “They heard the sound of gunshots and observed projectiles entering the home through the front door and living room wall/window area near the front door. The juvenile female struck by gunfire was fixing her friend’s hair at the vanity when she was shot in the throat. She ran to the bathroom where she collapsed.”

Witnesses told cops that Lewis, who was identified through surveillance video that showed her 2025 Hyundai Elantra allegedly coming and going from the scene, knew where her former acquaintance lived and was upset at her for stealing something with a male friend of theirs — a claim the person denied, the affidavit says.

They had “not associated for a couple months” after Lewis accused the person of the theft, according to prosecutors. The relationship between them “soured from there until they stopped speaking at all,” the affidavit alleges.

One witness said the person inside the home who knew Lewis also had a “falling out with Bailey over Bailey letting her get ‘jumped’ at a gas station months before the homicide,” according to the complaint. It’s unclear if any arrests or charges stemmed from the incident.

Detectives allegedly found social media posts linking Lewis to the person inside the home who knew her, and the former friend also identified her. Lewis was also linked to another shooting that allegedly took place 15 minutes earlier at an apartment building, with Lewis’ Elantra being spotted on video near that scene too, the affidavit says.

“It should be noted the drive time via Google Maps is between 11-18 minutes from location to location depending on the route you take,” the affidavit says. “This drive time aligned with the approximate time frame between the incidents if a car fired shots into [the apartment complex] and then drove straight to [the former friend’s home].”

In addition to murder, Lewis also faces multiple counts of accessory to armed criminal action and unlawful use of a weapon, prosecutors announced Friday. She was being held over the weekend on a $400,000 bond and was still at the Jackson County Detention Center as of Sunday, records show.
