Marcus Lawson (pictured, right), president of Global CompuSearch of Spokane, Wash., testified Wednesday that he found two photographs of naked women and Japanese "anime" computer animations on the hard drive of a Gateway computer in an upstairs bedroom used by Westerfield's 18-year-old son, David Neal Westerfield. The former Customs Service agent said that a detailed analysis of the files showed the pornography was downloaded at about the same time someone was accessing an email account belonging to the younger Westerfield. David A. Westerfield, 50, is charged with kidnapping and killing 7-year-old Danielle van Dam. He is also charged with misdemeanor possession of child pornography. Prosecutors have said the 80 or so images of child pornography taken from Westerfield's home indicate sexual interest in children.
Defense attorneys are trying to show that the defendant is not responsible for the pornographic images -- including those of young children -- found on his computer equipment.
David A. Westerfield, a 50-year-old self-employed design engineer, is on trial for the kidnapping and murder of 7-year-old Danielle van Dam.
Lawson told jurors that he examined copies of hard drives, zip disks and compact disks made by police and took numerous screen captures -- essentially photographs of what came up on the computer monitor at a given time.
Defense attorney Steven Feldman asked Lawson if there was a theme to the animations.
"A considerable number of the screen prints showed bondage -- where women were tied in ropes," Lawson said.
A screen print of an e-mail to a DNWesthotmail.com, as quoted by Lawson, said: "Thanks for joining anime.com."
Lawson also confirmed screen prints the defense entered into evidence last week, that a computer in the office of Westerfield's house was used to access pornography on Feb. 4 at 4:47 p.m., when the defendant was busy with detectives.
Feldman mentioned last week's suggestion that the clock on the computer may have been doctored.
"Did you see any evidence that that happened on any of the computers you examined?" Feldman asked.
"No, I did not," Lawson answered. He said there's usually signs when a clock has been tampered with, such as files being accessed before they were created. Nothing like that was apparent on Westerfield's computers, he said.
Tuesday, San Diego police Detective Johnny Keene testified that he collected Westerfield from his Sabre Springs home that Monday around 3:40 p.m. and took him to the Northeastern substation in Rancho Penasquitos. The defendant remained there until approximately 11:30 p.m.
