The gunman forced his way into the car, snatched Brittany Rock's cellphone from her hand and smashed his weapon across the right side of her face.
Rock's vision went black, but all she could think about was saving her little sister, Samantha Burnette, who was asleep in the back seat. Rock jumped out of the car and groped for the handle to her sister's door.
That's when her vision returned. What she saw next haunts her: The gunman shot her 16-year-old sister in the head as she woke up and tried to flee.
"She woke up to die," Rock, 20, recalled Monday. "They pushed my sister's body out of the car like she was a rag doll, and they drove off."
Burnette was fatally shot about 7:30 a.m. Sunday in an alley in the 700 block of Sims Avenue in St. Paul, according to police. A 32-year-old man and a 29-year-old woman were arrested several hours later in connection with the homicide, but the cases had not yet been presented to the Ramsey County attorney's office for charging consideration on Monday.
Police released few details about the homicide and motive, citing the ongoing investigation.
But Rock is certain: The woman who was arrested, whom Rock had considered a friend, set them and another friend up to be robbed.
"I hope … they pay for it," said Rock, "because they took an innocent child's life."
