WARSAW. N.Y. - A woman charged with killing a former friend in the Wyoming County Village of Perry has pleaded guilty to second degree murder.

Police say 38-year-old Kara Kastenhuber beat, stabbed, and strangled 33-year-old Desirae Withey in Withey's Borden Avenue apartment last February. They were both friends until Withey started dating Kastenhuber's ex-boyfriend.

In exchange for her plea, Kastenhuber will be sentenced to 15 years to life in prison in December.
