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

Update, 5:56 a.m. October 15: Since the heartrending confirmation Friday afternoon that a body found in Arvada last Wednesday had been identified as missing Westminster ten year old Jessica Ridgeway (see our previous coverage below), plenty of new information has cropped up in the search for what Westminster Police Chief Lee Birk described as "a predator in our community." Continue to get more details.

On Saturday, the Jefferson County Sheriff's Office circulated information about a possible child abduction in Golden, a community just south of Pattridge Park, the open space area where Jessica's body was found. Included was a photograph of the vehicle driven by the suspect, who described as being around twenty years of age, with longer brown. Here's that shot.

Soon thereafter, the young man turned himself in to authorities in order to clear himself from suspicion. According to him, he'd approached a thirteen-year-old boy to get information about his former girlfriend, not to snatch the child -- but because of the concerns raised by Jessica's case, his actions were misinterpreted as a possible kidnapping attempt.

Meanwhile, the Arvada Police Department released a pair of sketches involved in previous child abduction reports -- one from last year, the other in September. Here's a look at the sketches and accompanying descriptions, as shared by the Missing Cases Facebook page:

After the sketches' appearance, the Westminster Police Department issued a press release stating that at this time, the WPD "cannot make any connection between the sketch[es] and the Jessica Ridgeway case."

Yesterday, meanwhile, hundreds of people visited a memorial that sprang up in the vicinity of where Jessica's remains were discovered, as reported by 9News. And an online memorial to Jesscia is now visible at Memento.com. The background music on the site is "Jessica," a song by Regina Spektor that includes the lines, "Jessica, wake up..../We must get older now/So please wake up."

Here's an image from the site:
