Los Angeles ? Authorities searching a Long Beach park found the final missing body part — a severed head — believed to belong to a community college student killed and dismembered in a double murder-for-profit plot in Orange County, police said Sunday.

FBI agents and police from Costa Mesa and Long Beach searched El Dorado Park with cadaver dogs for two days before finding the head thought to be of Samuel Herr, 26, on Saturday, Costa Mesa police Sgt. Patrick Wessel said.

An arm and hand were found at the park Friday, and authorities had said the head was the only body part still missing. A coroner will officially determine whether the remains were Herr’s, Wessel said.

Herr’s Costa Mesa neighbor Daniel Wozniak, 26, is accused of killing and dismembering Herr and killing Herr’s friend Juri Kibuishi for money.

Wozniak was charged with two counts of murder Friday, just hours before he was scheduled to get married in another Long Beach park.

He was being held without bail Sunday at Orange County Jail. He was scheduled to be arraigned Tuesday.

Investigators believe Herr was shot and killed in a theater at the Los Alamitos Joint Forces Training Base. His torso was found in the theater’s attic May 21.
