Jessica Ridgeway predator search: Could killer have attended her memorial service?

Update, 8:36 a.m. October 9: As the search continues for Jessica Ridgeway, a new video has just been released showing the ten-year-old Westminster girl in the sort of candid, casual moment that can only energize the police officers, agents and others working on this case. See it below, followed by our previous coverage, which provides information from the Missing Jessica Ridgeway Facebook page about volunteer efforts and a pair of events slated to take place tonight.

Update, 5:48 a.m. October 9: The search is ongoing for Jessica Ridgeway, a ten-year-old Westminster girl who was last seen on Friday; see our original coverage below for more details. And while there have been no new breakthroughs since the discovery of what's thought to be Jessica's backpack, law enforcers and volunteers are still hopeful she'll be found safe -- a message that will be reenforced at two community events slated for tonight.

As we've reported, Jessica was last seen leaving for Witt Elementary School on Friday morning. Witt staffers left a message for Jessica's mom, Sarah, at about 10 a.m., letting her know that Jessica never arrived -- but because Sarah works nights and sleeps during the day, she didn't receive the message until about 4:30 p.m. At that point, police were informed, after which an Amber Alert was issued. A massive search in the Westminster area was expanded after Sunday, when it was announced that a backpack containing a water bottle with her name on it was found in Superior, more than six miles away from where she was last seen.

The latest? According to CBS4, about 125 officers from approximately a dozen law enforcement agencies, including the FBI, are taking part in the continuing search for Jessica. DNA evidence has been collected from the backpack, as well as from inside Jessica's home, for comparison purposes.

Meanwhile, volunteers are being solicited not to conduct the search itself, but to put up flyers of Jessica throughout the metro area. According to the Missing Jessica Ridgeway Facebook page, the online information center for the search, a volunteer distribution command post has been established at Westminster's American Furniture Warehouse location, at 9410 Wadsworth Parkway. Another item notes that the command post needs generators, utility extension cords, trash cans and outdoor lights.

Jessica Ridgeway has been missing from Westminster Colorado since 10-5 when she left for school, heading towards the park to meet up with friends she usually walks with but never showed to the park or to school. An Amber Alert has been issued and police are desperate for clues that may lead to Jessica.

On Saturday they found a back pack they have reason to believe belongs to Jessica.

Tonight, two vigils are scheduled for Jessica -- one in Westminster, the other in Superior. Here's a poster providing details:
