JUNEAU, Alaska (AP) - The attorney for a former Arizona legislator charged with killing a man on an Alaska hunting and fishing trip in 2016 says the shooting was an accident, not murder.

Deborah Macaulay, who represents Mark Desimone (dee-sih-MOHN), told jurors in closing statements that the lack of an apparent motive is a hole in the prosecution's case.

Desimone faces charges of murder, manslaughter and criminally negligent homicide in the death of Duilio (DOO-lee-oh) Antonio "Tony" Rosales.

Assistant District Attorney Amy Paige asked jurors to find Desimone guilty of first-degree murder.

Paige sought to cast doubt on defense testimony that questioned the safety of the gun used and the argument it unintentionally discharged.

Desimone resigned from the Arizona House in 2008 after being arrested in a domestic dispute with his then-wife.
