MILWAUKEE -

An Iraq War veteran who pleaded guilty to shooting his wife, a Milwaukee-area police officer, is scheduled to be sentenced.

Thirty-year-old Benjamin G. Sebena initially pleaded insanity. But he changed his plea in June after two doctors concluded that his mental-health issues weren't severe enough to justify an insanity plea.

He was convicted of first-degree intentional homicide, which carries a mandatory life sentence. However, the judge Friday will have the option of granting him parole eligibility after at least 20 years. Prosecutors have said they'll recommend Sebena not be eligible for parole for at least 50 years.

Sebena was convicted of ambushing 30-year-old Jennifer Sebena, a Wauwatosa police officer, as she conducted a solo pre-dawn patrol on Christmas Eve. He told investigators he was a jealous husband.
