(WKTV) - It's the first day of testimony and several witnesses have taken the stand in the murder trial of Clayton Whittemore.
The New Hartford man is accused of killing his girlfriend, Alexandra Kogut, in her SUNY Brockport dorm room.
One of Thursday's witnesses was Kogut's college roommate, who spoke about the relationship the couple had.
In seven hours, Monroe County jurors heard testimony from seven witnesses, including the first police officers who responded to Room 108 at McLean Hall at SUNY Brockport. University police officers said they saw Kogut and Whittemore together on campus the night of Sept. 28, 2012, and that they had ticketed Whittemore for having an open bottle of beer.
A student working at the front desk of the building testified she saw Kogut and Whittemore arguing. When police went to check on the welfare of Kogut in the early morning hours of Sept. 29, they found her lying on the floor.
The police evidence technician, who processed the small 13-by-15 dorm room that was the crime scene, found a broken bloody iron, a blood-smeared beer bottle, a broken pencil and pen, dented Old Spice can and bloody razor.
It is likely the defense will use these to support their theory that Whittemore was acting under the influence of an extreme emotional disturbance when he killed Kogut.
Also on the stand Thursday was Kogut's roommate, who stayed in another room the night Whittemore visited. She woke the next morning to 20 missed calls on her cell phone.
She testified that she told a psychologist that Kogut and Whittemore's relationship seemed normal, and that Kogut looked forward to his visits.
Testimony will resume Friday.
