BUFFALO, N.Y. (AP) — A New York man who stabbed his girlfriend to death has been sentenced to 25 years to life in prison.

An Erie County Court judge sentenced 50-year-old John Avent of the town of Tonawanda (tahn-uh-WAHN-duh) on Wednesday.

A jury convicted Avent of second-degree murder in March, a year after 51-year-old Roberta Rybinski was killed in the couple's apartment.
