OMAHA, Neb. (AP) — An Omaha man has been sentenced to life in prison for fatally stabbing his on-again, off-again girlfriend more than a year ago.

Robert Grant was sentenced Tuesday for the September 2013 stabbing death of 43-year-old Trudy McKee. Prosecutors say Grant stabbed McKee more than 40 times.

Jurors in Douglas County District Court found Grant guilty of first-degree murder and weapon use in October. Grant didn’t attend the conviction hearing after he allegedly punched his attorney and a sheriff’s deputy during his trial for McKee’s death.

Grant was not present at the sentencing hearing.
