ERIE, Pa. — Two young girls accused of brutally attacking another girl on a playground are too emotionally immature to understand the criminal charges against them, and the charges should be dismissed, their attorneys said. The girls, ages 10 and 11, face aggravated assault and other charges for the attack on another 10-year-old girl at an elementary school playground on the evening of April 3. The girls are accused of stomping on the victim and breaking her hip, police said. Erie County Public Defender Tony Logue says he will ask a Juvenile Court judge to dismiss criminal charges against the 10-year-old girl. “How can my attorney effectively communicate with his clients given the client’s chronological age versus emotional age?” Logue said. Attorney Bruce Sandmeyer said he has similar concerns for his client, the 11-year-old, and expects to file a similar motion in the coming days. “My client is just 11 years old and just an elementary school student,” Sandmeyer said.
