The 14-year-old niece of John O'Keefe testified today at the murder retrial of Karen Read.
She and her younger brother lived with O'Keefe for several years after their parents died.
The young teen told jurors the last few week's of their uncle's relationship with Read included frequent verbal arguments and increasing tension.
Read is accused of hitting O'Keefe with her SUV after a night of drinking and leaving him to die in a snowstorm.
