DAKOTA CITY, Neb. (AP) — A 23-year-old Iowa man convicted of killing a northeast Nebraska woman has requested a new trial.

The attorney for Raymond Gonzales Jr. filed the motion on Wednesday. The attorney says problems with the trial include jury misconduct and a verdict not supported by sufficient evidence.

A jury on Dec. 9 found Gonzalez guilty of first-degree murder and use of a firearm to commit a felony. Authorities say he shot 28-year-old Bonnie Baker 16 times in December 2013 at a party in her South Sioux City home.

Witnesses say Gonzales became upset after people at the party teased him.

A district judge has ordered a hearing on the motion for Feb. 5, the same day Gonzales is scheduled to be sentenced.
