Moments after an SUV in which she was riding pulled into a driveway in the Upper East Side neighborhood Palm Grove Thursday evening, 20-year-old Diana Louissant was shot to death by a gunman who opened fire into the vehicle, said Miami Police Sgt. Freddie Cruz.

Police responding to the scene just before 6 p.m. at 5951 NE 5th Avenue in Miami established a perimeter, Cruz said, but the gunman had already fled in an unknown direction, possibly in black vehicle.

Several passengers were in the red Chevy SUV, but only Louissant was seriously injured.

"This group of individuals were arriving at this home," Cruz told CBSMiami. "When they arrived they were met by a black male, tall with brown hat, fired seven, maybe eight shots into the vehicle, fatally hitting one of the passengers.. She was struck twice."

Louissant's family is expected to make a public plea for information related to her murder Friday afternoon.
