WUSA9's Andrea McCarren was in the District courtroom for the appearance of Jamieson Tymann, 21. In an exclusive, Tymann's lawyers offer a different version of events.


Tymann's lawyers argued that American University students are now on spring break so key witnesses to the incident would not be available to testify.

The American University student and Pi Kappa Alpha fraternity member was a part of a house party, Jan. 15, 2016. The massive frat party in Bethesda, Md. was broken up by police.

"He was arrested and ended up with stitches as a result of his arrest," said Tymann's lawyer, Steven Kupferberg.

Charging documents reveal Tymann became agitated after a Montgomery County Police Officer repeatedly asked him to leave. He allegedly slugged the officer in the chest and in the eye.

Tymann's lawyers argue there is another version of events. And they will rely on 7.5 hours of police body cam video they have obtained.

"We haven't had an opportunity to review all the tape, but there is more than one point of view as to what happened that night," said Kupferberg.

"Our client is a fine young gentleman, never been in trouble before. His version of what happened is different from what the police have alleged," said Kupferberg.

At the January party, police found more than 200 people just on the first floor. Another 75 huddled in the garage. Tymann will be back in court on April 12th, which happens to be his 22nd birthday.

The frat house is leased to American University student Tyler Steinhardt. He will be in court this spring on charges he provided alcohol to 110 minors.
