A young girl testified this week at the murder trial of the man accused of attacking her and her friend inside an elevator in Brooklyn.

11-year-old Mikayala Capers says she had just finished a game of tag and was headed upstairs for Italian ices with her friend, Prince Joshua Avitto, back in June of 2014, when a mysterious man followed the pair into an elevator.

She says he yelled at them and then began to repeatedly stab them. 6-year-old Prince Joshua did not survive. Mikayla was severely injured.

Prosecutors say that man is Daniel St. Hubert, who is now standing trial for murder. They say he was identified by witnesses, seen on nearby surveillance video and his DNA matched a bloody steak knife that was recovered. However, defense attorneys say Mikayla is lying.

"Those are not real tears if you look," said defense attorney Howard Greenberg. "The press told her to who to pick. Her reality of these events is what she saw on TV.

"She will live with that face for the rest of her life," said Regenia Travathan, Capers' Great Grandmother. "The nightmares, the trauma that she lives with. How dare he? We're just going to wait to make sure justice is done, and it will get done"

The defense hammered Capers on her memory of the incident, her 9-day hospital stay and whether she recognized St. Hubert from news coverage.

If found guilty, St. Hubert could spend the rest of his life behind bars.
