HILLSBORO, Ore. - Friends and family of both the victims killed and of the teenager accused of killing them, packed the courtroom Thursday for opening statements.
At this point there is no question what led to the deaths of 6-year-old Anna Deiter-Eckerdt and her 11-year-old sister Abigail Robinson.
Last October the two were playing in a pile of leaves when they were run over. Cinthya Garcia-Cisneros, 19, admits to driving the car into the leaves and feeling a bump.
Prosecutor Bracken McKay said: "This defendant didn't do the right thing that night. ... Hold her accountable for her choices."
The defense claims she didn't know she hit the girls and was in shock shortly after. And that's the reason why she did not report the accident or offer help to the girls.
Prosecutors started making the case that she knew what happened because her brother had told her. And that's when she drove the car away to avoid police and went out for ice cream.
"It's a decision she'll have to live with the rest of her life, and the consequences she'll have to live with the rest of her life," said Garcia-Cisneros' defense attorney Ethan Levy.
Prosecutor Bracken McKay said: "The obligations that kick in after you are involved in an accident and that is what the case is limited too."
Garcia-Cisneros' boyfriend, Mario Echeverria, was the passenger of the SUV. He already pleaded guilty to tampering with evidence because he didn't report it and he had the car washed after the crash.
Garcia-Cisneros is facing two felony charges of failure to perform the duties of a driver after a crash.
The trial is expected to wrap up early next week.
Garcia-Cisneros faces up to 18 months in prison if convicted.
