A Rifle High School student has been issued a summons in the Feb. 23 attack on a 14-year-old girl, and several other students are under investigation in the incident.

Rifle Police Lt. J.R. Boulton said today the juvenile summons for assault has been served on a female student. He said he couldn't provide more details because it is a case involving juveniles.

The injured girl's father, John Kuersten, said this morning said school officials didn't call him or his wife until nearly two hours after his daughter was jumped by several students and beaten severely, and he blames a ''gang mentality'' that has gone unchecked at the school.

''She's absolutely not going back to Rifle High School,'' he said. ''She's doing well, but she'll have some scarring.''

He said his daughter's injuries included a broken nose, two black eyes, scratches over her face, whiplash, separation between two of her vertebra and a bruised collarbone.

''We had to take her to the emergency room and file a police report ourselves,'' he said. ''The school didn't do anything.''

A call to the school principal was not immediately returned.

Kuersten and his wife, Alice, told a crowded school board meeting last night that violence is a big problem in the high school, but he said the district ''downplays every incident. The teachers are afraid for their jobs and everybody's trying to keep it quiet.''
