A student arrested last month on charges of assaulting police pleaded guilty to four counts of assault and must serve 12 months of probation and apologize to the two Waltham police officers involved in the March 25 altercation, according to court documents.Kathryn Schill '06, a 21 year-old psychology major from Longmeadow, Mass., entered her plea at a May 10 hearing in Waltham District Court.

She was arraigned March 27 on three counts of assaulting a police officer and one count of assault and battery with a dangerous weapon following an incident two days earlier in which Schill spit at and bit the hand of Officer Kristen Philpott and punched Officer John Connarton.

The most serious count of assault and battery with a dangerous weapon was reduced to assault and battery-a charge which resulted from Schill kicking Philpott with the Uggs boots she was wearing at the time.

In addition to writing letters of apology to Philpott and Connarton, Schill was ordered to undergo drug and alcohol screenings at the discretion of her probation officer. She had been described as highly intoxicated during the altercation in a police report compiled by Philpott.

Schill has declined numerous request to comment for any articles in the Justice.

According to the report, Schill had been handcuffed by Brandeis police and was lying on the ground when Waltham police arrived on scene.

Philpott assisted officers in trying to get Schill to sit up, but she was "constantly yelling and screaming at all officers present," Philpott wrote. Schill exclaimed to police that she was only trying to go home, and the police were violating her rights. She began squirming, the report says, trying to get out of the handcuffs, and soon began spitting on the officers.

While Schill was being forced into a police car, she started spitting again. Philpott wrote that she placed her hand over Schill's face to stop her from spitting, only to have Schill begin biting the palm of her right hand "for approximately 10 seconds without releasing."

While trying to restrain Schill in the back seat of the police car, Philpott reported that Schill kicked her several times in the face "causing the skin [to] break and bleed."

Emergency medical technicians transported Schill to Newton-Wellesley Hospital, where she had another altercation with police.
