SAN DIEGO -- While friends and relatives of the van Dam family continued to urge the community to help search for Danielle Friday, police decided to move their investigation headquarters out of the Sabre Springs area.

The base of operations was moved away from the home from which Danielle disappeared to San Diego police headquarters in downtown San Diego.

"We based (the investigation) out of Northeastern initially because most of the people detectives needed to talk with lived or worked in that area," San Diego Police Department spokesman Dave Cohen said. "For the most part, those contacts have been made."

Cohen said the move makes logistical sense because many of the 40 or more detectives assigned to the case are based downtown and will have access to their regular offices, computers, and support personnel.

Police also said they found "nothing of significance" in their search of the desert in Imperial County, and that they had no plans to resume their full-scale search of the desert.

Volunteers Set Up Meeting To Address Search Efforts

Friends of the van Dam family Friday put out a call for more citizens to join the search for Danielle.

Brenda van Dam Pleads For Help Finding Danielle

Volunteers helping authorities look for missing Danielle held a meeting to discuss their efforts Friday night.

Ribbons -- in pink and purple, Danielle's favorite colors -- and posters of Danielle's smiling face are showing up all across the San Diego area but family friend and spokeswoman Susan Wintersteen told 10News "there needs to be more."

"Every car needs to have a ribbon tied on its antennae. We need to have (posters) at every signal and stop light ... we want it out there everywhere. We want it down in Mexico, we want it up in Canada, we want it as far across the country as we can," Wintersteen said.

A $10,000 reward is being offered for information leading to the girl's safe return home.

Police officials asked anyone with information on the youngster's whereabouts to call (619) 531-2000.

The family also has set up a hot line for tips at (888) 664-6664. They have also asked that people visit the Web site: DanielleMissing.com

Media Surrounds David Westerfield Keeping Tabs On Westerfield's Movement

Detectives paid another visit to the home of David A. Westerfield, 50, (pictured, left) Thursday evening, leaving about 15 minutes later without commenting on the reason for the visit.

Westerfield, who lives two doors from the home of the missing girl's family, has not been charged. Earlier Thursday, he hired criminal defense attorney Steven Feldman.

Westerfield ventured out of his home again Friday, apparently to go meet his newly hired attorney.

Getting out and moving through a mob of reporters and television cameras toward his front door, he said: "I can't comment; he's asked me not to say anything," apparently referring to Feldman.

When reporters asked Westerfield outside his home earlier this week if he knew where Danielle was, he shook his head, said no and walked inside.

Detectives Thursday again went to a desert locale in Imperial County, where Westerfield said that he camped last Saturday and Sunday. More than a dozen San Diego Police Department and San Diego County sheriff's personnel scanned the sun-blasted terrain on the ground and from helicopters, assisted by law enforcement officers from that region.

Cohen said that he did not know if the multiagency search crews turned up "anything of significance," he said, but they "did not locate Danielle van Dam."

SDPD officials also spent the day following "scores" of leads they've uncovered since Saturday, Cohen said.

On two occasions, investigators with police dogs have gone through Westerfield's home.

Authorities continue to refer to Westerfield only as a "potential suspect" in the case. However, they appear to be placing pressure on him -- making regular visits to his home that spark frenzy among the platoon of reporters and photographers camped out in front of the house.

Police officials have repeatedly said that they do not consider the parents suspects in the girl's disappearance, though they point out that no one has been completely ruled out.
