A 37-year-old woman was killed early on New Year's Day in what Alaska State Troopers are calling a homicide.

Wasilla resident Amy Smith died on Monday morning. Alaska State Troopers and emergency responders got a report at 4:54 a.m. that CPR was being performed on Smith.

An autopsy the next day "indicated the cause of death was homicide," troopers said. Anthony Smith of Wasilla, 38, was arrested around 4 p.m. on Tuesday. He was taken to the Mat-Su Pre-Trial facility, where he was being held without bail, according to troopers.
