Sergio Marciano Cox, 26, was killed during a home invasion at the Princeton Square Apartments in Jacksonville, Florida, on November 11, 2016. Officers were called about 1 a.m. and reported receiving a description of a vehicle leaving the scene; they stopped the car and found Sergio deceased inside while his brother, Lucky Marcel Cox, was driving.

Investigators concluded Sergio died during the commission of the home invasion that he was allegedly carrying out with his brother. It was unclear whether Sergio was killed by someone inside the apartment or by actions taken by Lucky during the attempted robbery. Lucky, 28 at the time, was initially arrested at the scene for possession of marijuana and driving with a suspended license, then later became the subject of an arrest warrant charging him with second-degree murder, burglary with assault, and attempted home invasion robbery.

What does anyone know about the events earlier that night at Princeton Square Apartments or about the vehicle that was stopped?
