Andrew Ryan Cassell, 25, pleaded guilty Monday to vehicular manslaughter in connection with an Oct. 31 crash that caused the death of Aldina Ekic, 21.
Cassell, who was accused of driving drunk, had been scheduled to go to trial next month. The change of plea came during a pretrial hearing before Fourth District Ada County Judge Deborah Bail.
Cassell faces a sentence of up to 15 years in prison and a $15,000 fine. He is scheduled to be sentenced April 30.
Ekic died from blunt force trauma to the head. She was pronounced dead at the scene of the crash scene on State Street near Glenwood Street.
Cassell had a blood alcohol level of .125 percent, more than 50 percent above Idaho's legal limit of .08 percent, prosecutors said previously.
Cassell has been out of jail since posting $75,000 bond in early November. He is prohibited from driving and from drinking.
