Police baffled by disappearance of Colorado 12-year-old

(NBC) – Investigators sent dive teams into a pond on the southwest side of Greeley, Colorado in what they called the initial search of a vital area as they look for a 12-year-old girl who has been missing for nearly a week.

Kayleah Wilson was last seen last Sunday at about 3:40 p.m. when she left her home to walk to a friend's birthday party across a busy highway about a mile from her home.

Saturday, a dive team searched a pond near the Homestead Lakes area in Greeley around 3:30 p.m. for any signs of the missing sixth grader.

Firefighters with the Union Colony Fire Department were at the pond with the FBI. Investigators also brought in sonar equipment.  They finished their search of the pond after 4 p.m. The pond is about six blocks away from where Kayleah went missing.

The Weld County posse, a group of officers on horses, also searched the area. The mounted officers started at Greeley West High School and moved south in their search. Investigators called off the search for the day around 5 p.m.

"We're still in the same place we were yesterday, pretty much the same stance. We are looking for something to tell us that she was either abducted or she's a runaway. We still don't know that for sure yet," Greeley Police Sgt. Joe Tymkowych said. "That's kind of the concern that has us at a point now where we really, every little piece of information, every little piece of evidence, we're combing through it and going over it two or three times, making sure."

More than 600 motorists passing near the area Friday were stopped by Greeley Police and asked if they had seen anything Sunday night.

Tymkowych says authorities have gone to Kayleah's favorite hangouts, searched along the highway, interviewed friends, family, and acquaintances, and have contacted registered sexual offenders who live nearby.

Both Greeley Police and the FBI have repeatedly made pleas to the public for any information on her whereabouts.

They say they do have some leads, but cannot comment on them.

Both Greeley Police and the FBI say a news conference held on Friday generated more callers and they are following up on many new leads.

Investigators also released pictures of Kayleah's inhaler, which is red and white, so they are asking people to be on the lookout for that as well.

Kayleah is described as 5'1", 145 pounds, with brown eyes and brown hair. She was last seen wearing a white and pink shirt over a white tank top, blue jeans and white and red shoes.

She is a student at Brentwood Middle School.

Anyone with information about this case is asked to contact the Greeley Police Department at 970-350-9600. Or you can call 1-800-CALL-FBI.
