(CBS/AP) ROCHESTER, N.Y. - Police say Clayton Whittemore, a New York college student accused of killing his girlfriend, told them he "just snapped" and killed Alexandra Kogut with his fists and a curling iron while visiting her college dorm last month.
A Monroe County Sheriff's Office report released Wednesday says Whittemore, 21, detailed the killing to an officer on Sept. 29, after his arrest earlier that day.
According to the report, Whittemore said he and 18-year-old Kogut got into a shoving match while arguing over "stupid stuff" in her room at the State University of New York College at Brockport. According to CBS affiliate WROC, Whittemore said Kogut was continuously rude to him earlier while they were at a friend's house.
After the fight turned physical, Whittemore said he snapped and started to hit her "over and over with my fists," WROC reports. He told the officer Kogut began to have breathing problems, so he began hitting her with a curling iron.
"I didn't want the girl I loved to suffer, so I started beating her with the curling iron until the noise stopped," Whittemore reportedly said.
The Utica College student pleaded not guilty during his initial court appearance. His arraignment on a murder charge set for Oct. 25.
