FOREST GROVE, Ore. – Two teens were arrested Tuesday evening in connection with the deaths of two young Forest Grove stepsisters, police said.
Abigail Robinson, 11, and her 6-year-old stepsister, Anna Dieter-Eckerdt, were playing in the leaves along a roadway near their home when they were struck by a vehicle Sunday night.
Cinthya Garcia Cisneros, 18, of Forest Grove was arrested Tuesday with her boyfriend, 18-year-old Mario Echeverria of Cornelius, according to Capt. Mike Herb of the Forest Grove Police Department. Police said a tip from a citizen who saw news coverage of the girls' deaths provided the information that led them to the pair.
Cisneros was allegedly driving the vehicle and lives just a couple blocks from where the girls were hit, Herb said. Echeverria was one of two passengers. The other passenger has not been charged at this time.
Cisneros was charged with two counts of hit-and-run.
Echeverria faces charges of tampering with evidence and hindering prosecution. Police said the suspects were not truthful when first questioned. He was released on bond Wednesday.
Police said Abigail's father, Tom Robinson, had been taking photos of the girls as they played in the leaves. He went in the house briefly, heard a car go by and came out to find the girls had been hit and were injured. His wife Susan Deiter is Anna's mother and he is her stepfather.
Anna died at the scene. Abigail died at Randall Children’s Hospital Monday night.
Police showed a photo of the 2001 Nissan Pathfinder SUV they believe hit the girls. They'd like to hear from anyone who may have seen it Sunday night. Police said the Pathfinder belongs to a parent of one of the passengers.
Cisneros graduated from Forest Grove High School in 2012 and Echeverria graduated this past spring, according to the school district.
