A New Hampshire man sentenced to 38 years in prison in Maine for killing his former fiancee is asking Maine’s highest court for a new trial or acquittal. A lawyer for Jason Twardus of Rochester, N.H., told the Supreme Judicial Court on Wednesday that the prosecution never shared evidence about possible alternate suspects in the killing of 30-year-old nursing student Kelly Gorham in 2007. The lawyer said more evidence of that emerged after trial. The prosecutor countered that the evidence against Twardus was “overwhelming.” The court did not immediately rule. Gorham was living in Alfred, Maine, when she disappeared. Her body was found a month later buried on property in northern New Hampshire owned by Twardus’ father. Prosecutors said Twardus was upset over their breakup. Twardus’ two previous appeals were denied.
