Darby Marmillion, a 19-year-old white female, was shot during a transaction in Baton Rouge after arranging to meet someone online to buy vape pens. The meeting took place the evening of April 2, 2026, at the City Heights Apartments on Coursey Boulevard. Investigators say the 16-year-old entered Marmillion’s vehicle, displayed a handgun, robbed her of the vape pens, and shot her. She was taken to a local hospital in critical condition and died on April 3, 2026.

Authorities arrested a 16-year-old male identified as Brandon Lewis on April 6, 2026. Because he is a juvenile, his name and photograph were not widely released; he was booked into the Juvenile Detention Facility and faces charges including first-degree murder, armed robbery, illegal possession of a handgun by a juvenile, and obstruction of justice.

The case centers on an in-person meeting arranged through an online connection that turned deadly. Did anyone in the Baton Rouge area see or hear anything at City Heights Apartments on the night of April 2 that could help investigators?
