Woodward and Bernstein had attended the Orange County School of the Arts together.
Orange County District Attorney Tony Rackauckas said Woodward won't appear in court until Tuesday, adding that he was not ready to say what charges Woodward will face, the Los Angeles Times reported.
University of Pennsylvania sophomore Blaze Bernstein, pictured right, went to the park with high school buddy Samuel Woodward Jan. 2, authorities said.
Bernstein, who went missing on January 2, was found dead in a shallow grave around the perimeter of Borrego Park earlier this week.
Woodward was the last person to see Bernstein alive, Barnes said.
"We do believe Mr".
Woodward, who was questioned by police in the case, is a friend of Bernstein, authorities say. He also would not discuss the condition of Bernstein's body, which was found in a shallow grave in some brush.
Investigators said they were working to determine a motive in the crime.
The suspect was identified as 20-year-old Samuel Woodward. She did not identify the suspect or provide any other details.
Mourners embrace as they join more than 300 people in Borrego Park in Foothill Ranch, Lake Forest on Wednesday, Jan. 10, 2018 for a candlelight vigil for Blaze Bernstein. His wallet, credit cards, glasses and cash were all found in his room. "With his death, a attractive life has been extinguished". A woman, speaking from behind the door, said she had "no comment to make". "Our words can not express how grateful the family is to the community here in Orange County and all over the world for expressing their love and support during the past very hard week".
"Finally. My thoughts are: Revenge is empty".
"Nothing will bring back my son so we ask the world to please honor Blaze's memory by doing an act of kindness today - don't wait - do it now", the grieving mom told the Los Angeles Times. "My only hopes are that he will never have the opportunity to hurt anyone else again and that something meaningful can come from the senseless act of Blaze's murder", her statement said, in part.
Not long after in the early afternoon, two sheriff's investigators walked with Woodward - handcuffed and wearing a black sweatshirt reading, "Keep the peace" - from a parking area in the Civic Center to the Orange County Jail, where he is being held without bail.
Woodward told investigators that he left the park after Bernstein went out and didn't return or respond to social media messages. The friend said he seemed depressed, but didn't say he wanted to hurt himself. He alleged he returned to the park several hours later but could not find Bernstein. In the affidavit, the investigator wrote that the friend said the scratches on his hands and dirty nails were from a "fight club" he was involved in.
According to a search warrant affidavit obtained by the OC Register, detectives who spoke to Woodward two days after Bernstein's disappeared noticed that his hands appeared to have small scratches on them and he appeared to have "dirt under his fingernails".
The Register reported, based on an affidavit signed by police investigators, that the suspect was "visibly shaking" in one interview.
At one point, Woodward opened the doors to his rental vehicle and allowed two detectives to look inside, according to the affidavit.
