CONCORD (AP) – The resentencing hearing has concluded for a New Hampshire man sentenced as a teenager to life in prison without parole for killing his parents.

Foster’s Daily Democrat reports testimony in Strafford County Superior Court wrapped up Tuesday in the case of 39-year-old Robert Dingman. Dingman was sentenced to life in prison when he was 17. He and his 14-year-old brother, Jeffrey, shot their parents in 1996.

The Attorney General’s office wants Dingman to serve 50 years while the defense says he should serve 25 years.

A forensic psychologist argued Dingman shouldn’t be treated the same as an adult murderer because his brain was not fully formed.

The judge says she will issue a new sentence in the coming weeks.
