TOPEKA, Kan. (AP) — A Topeka man has been sentenced to nearly 13 years in prison for killing his girlfriend.

The Topeka Capital-Journal  reports that the sentence for 23-year-old Trevor William Adkins was handed down Wednesday. He pleaded guilty in November to intentional second-degree murder in the death of 22-year-old Lacie Atchison.

Atchison’s body was found at the top of a wheelchair ramp outside their home in September. She had been stabbed 50 times.

Officers were called after neighbors reported seeing a naked man fighting with another man in the neighborhood. The couple’s young daughter was inside the home but was not hurt.

Adkins told police he was on a “bad trip” after consuming methamphetamine and other drugs.

Adkins was originally charged with first-degree murder before reaching a plea deal with prosecutors.
