The community is on alert for strangers because of the disappearance and murder of 10-year-old Jessica Ridgeway in Westminster.
Ridgeway disappeared Oct. 5 as she was walking to meet up with friends at Chelsea Park so they could all walk to school together. The park is several blocks from her home. Her friends said she never showed up at the park and the school reported her absence to her mother that morning.
However, Jessica's mother, who had been working the night shift, slept through the calls and didn't realize her daughter was missing until 4 p.m.
Hundreds of investigators are working the case, trying to find Jessica's killer.
Investigators are now working their way through nearly 4,000 tips and encourage anyone with any information to come forward. A tip from the community could break the case, authorities said.
FBI spokesman Dave Joly said the suspect could "be your boss, your friend" or a family member.
The FBI Behavioral Analysis Unit said that often, someone in the community will unknowingly be associated with the offender of the crime, and may be in a position to observe behavioral changes in that person.
They will recognize the changes, and may even question the person about it, but may not relate the changes to that person’s involvement in the crime. [Read the complete profile.]
Other Incidents In Arvada
Although police have said they don't believe a person is abducting children at random, they are aware of a case in which a white van approached children in Arvada on Oct. 4. In September, two other child enticement attempts were reported by Arvada police.
In the Oct. 4 incident, Malachi Martinez said a white van tried to get the attention of his children as they walked home from Lawrence Elementary. Arvada Police confirmed the incident was reported.
"It felt like we were getting followed by the car," said Raina Camacho, a sixth-grader at Lawrence.
"We started running and the car turned around the other street and parked in front of us," said Camacho's sister, Sierra, a fifth-grader. "We went to the fire department, but we saw the fire truck leaving. So we ran back to school. We told the principal what happened and she called the cops."
In the September incidents, the kids reported seeing a blue four-door sedan. 7NEWS has learned a third September report of a suspicious, slow-driving vehicle was never shared with the public because after two days of investigating it was found to be a misunderstanding.
"(A man's) dog had gotten out of the yard and he was driving around looking for his dog," said Arvada Police Department spokeswoman Jill McGranahan.
