It's this appearance that the suspected killer used to show that he owned gold ball earrings.
The jewelry is a key part of the prosecutor's case against Alcala involving 12-year-old Robin Samsoe. She was kidnapped in Huntington Beach in 1979, and her remains were later found not far from Alcala's Monterey Park home.
Samsoe's mother has testified the earrings were worn by her daughter. They were discovered in Alcala's storage unit in Seattle where he moved after her murder.
The 66-year-old was on the stand as both his own attorney and witness often starting his questions with, "Mr. Alcala, what did you do next?"
He admits that he photographed young women at the beach, but he tried to show that he was at Knott's Berry Farm later that day when Samsoe disappeared.
Alcala is also accused of murdering four women in L.A. County in the 1970s. Prosecutors allege DNA links him to them.
Dedee Parenteau sat in court for her sister Jill, allegedly murdered by Alcala just days before Samsoe's abduction.
"She was very kind. I don't think there was a mean bone in her body. What's hard for me is to know that that was last face she saw in her life. The hatred I have for him actually that he could be so evil," said Parenteau.
Alcala continues to testify in his own defense while acting as his own attorney. He still faces cross-examination by the prosecution Wednesday.
