COSTA MESA — The head of a 26-year-old Costa Mesa man who was killed and dismembered was discovered about noon Saturday in brush at El Dorado Park in Long Beach, police said.

Authorities believe that Samuel Eliezer Herr was killed May 21 and his body dismembered.

Daniel Patrick Wozniak, 26, was arrested Wednesday night at a Huntington Beach restaurant and charged Friday with two felony counts of special circumstances murder over the deaths of Herr and Juri “Julie” Kibuishi, 23, of Irvine.

Kibuishi’s body was found May 22 at Herr’s apartment. Police initially suspected Herr in the killing, because he had disappeared.

Parts of Herr’s dismembered body have been found at El Dorado Park and at Los Alamitos Joint Forces Training Base.

Members of the Costa Mesa Police Department, the Long Beach Police Department and the FBI continued conducting a search of El Dorado Park for more evidence, police said.

When Wozniak was arrested Wednesday night, he was only suspected as an accessory. Herr was still the suspect, said Det. Sgt. Ed Everett of Costa Mesa police. But after interviews with Wozniak and further investigation, police found Herr’s body, and Wozniak became the suspect.

After Wozniak was transferred to the Orange County Jail on Thursday, he hurt himself, sustaining a head injury, Lt. Mark Manley said Saturday.

Costa Mesa police put out a version of events Friday. Around 1 p.m. on May 21, Wozniak and Herr drove to the Los Alamitos Joint Forces Training Base, where Wozniak shot and killed Herr at the base’s theater facility to rob him, police said.

Wozniak then cut off Herr’s head, left arm, and right hand, police said. Herr’s torso was discovered Thursday in a seldom-used portion of the theater. Police said that Wozniak disposed of other body parts at El Dorado Park.

Wozniak then set up a meeting with Kibuishi at Herr’s apartment by sending text messages from Herr’s phone, police said.

Shortly after midnight, Kibuishi went to Herr’s apartment at the Camden Martinique complex at 2855 Pinecreek Drive in Costa Mesa, where Wozniak met her, police said.

Inside the apartment, Wozniak shot her in the head with a shotgun, killing her, police said. He then removed some of her clothing to make it look like a sexual assault, police said.

On Saturday, Herr’s father went to the apartment to check on him and found Kibuishi’s body. Police discovered text messages that showed Kibuishi had gone to the apartment voluntarily and began looking for Herr.

They found that somebody was using his card to make ATM withdrawals in Long Beach. That led them to a 17-year-old boy, who told police he was making the withdrawals for Wozniak.

Noah David Buffett, 28, of Long Beach, and Wozniak’s brother, Timothy Wozniak, were arrested on suspicion of accessory after the fact. They are suspected of helping dispose of evidence other than the body, Everett said.

The only known motive for the crime is financial gain, Everett said. Around $2,000 was withdrawn from Herr’s account.

Wozniak was scheduled to get married this weekend, police said. He is currently being treated at Western Medical Center, prosecutors said.

A video of Wozniak surfaced Saturday showing a smiling and laughing man during apparent outtakes for a 2009 play he starred in (http://bit.ly/cFirFI) and a Facebook profile for a “Dan Wozniak” showed that he became friends on the social networking site with a “Julie Kibuishi” sometime between March 22 and April 5.

Wednesday morning, the day he was arrested, he was making jokes on a friend’s Facebook profile. A friend wrote “No help cmon I need something to paint people!!!” and Wozniak replied “I suggest Santa Claus trapped in a snowstorm…come on…think about it!”

When Wozniak was arrested two weeks ago on another matter, he listed his profession as actor. He was the star of a recently completed production of “Nine” at Hunger Artists Theatre Company in Fullerton.

The OC Weekly raved, “Dan Wozniak’s Guido is superb. Though his character should be an unlikable pig — he’s self-obsessed, egotistical and a liar who uses women as checkers pieces —Wozniak somehow manages to make Guido eminently likeable and even sympathetic. … Wozniak captures the angst of a man staring into the abyss of his own being and seeing his own frailty.”

Police asked that anyone with additional information contact Everett at 714-754-5395 or Det. Jose Morales at 714-754-5637.
