JUNEAU, Alaska (AP) – Prosecution and defense attorneys say a former Arizona lawmaker fatally shot a man during a hunting and fishing trip in southeast Alaska in 2016. But they disagree on how and why the shooting took place.

Opening arguments were held Friday in the trial of Mark Desimone. Desimone is charged in the death of Duilio Antonio “Tony” Rosales.

Assistant District Attorney Amy Paige says Desimone was doing day labor at a local jewelry store where Rosales worked.

The owner of the store invited Desimone, Rosales and others on the trip. She says Desimone became moody when he learned Rosales was coming.

Desimone’s attorney, Deborah Macaulay, says she’ll present evidence that doesn’t require jurors to conclude Desimone killed someone he barely knew for “virtually no identifiable reason.”
