SPOKANE VALLEY, Wash. -

Police are investigating a possible case of child luring after a 12-year-old girl says a man in a truck approached her Thursday as she walked home from Opportunity Elementary.

Last Saturday night, the girl and a 10-year-old friend were having a sleepover in a camp trailer on her family's property when, according to a Spokane Valley Police Department press release, the girl said a man was standing outside looking into the trailer.

The man allegedly knocked on the door and tried to open it. The girl called her parents on her cellphone and when her dad came outside the man was gone. The girls went inside the house and a minute later they all heard a loud knock at the front door. When the dad went to the door, no one was there, police said.

On Thursday the 12-year-old girl told police she saw a man driving a newer, full size, dark blue truck, pulled up next to her by the sidewalk as she was walking home from school. She claimed the man spoke to her, and she yelled at him to leave her alone and ran to a neighbor's yard.

According to the victim he then placed a handgun on the dashboard and told her to calm down. Police said the girl told the man to leave her alone and he eventually drove away eastbound down 10th Avenue.

Investigators say the man was driving a newer, full size, dark blue truck and they describe him as being white, in his 30's, with a stocky build and a dirty blonde beard.

Anyone who may have seen this truck or suspect in the area of Opportunity Elementary matching the descriptions is urged to call Crime Check at 509-456-2233.
