Police in a Colorado town where the body of a missing 10-year-old girl was found want to question a teenage suspect in two unsolved child enticement cases.

Arvada police spokesman Sgt. Mark Nazaryk Friday says a sketch developed in the September incidents bears some resemblance to 17-year-old Austin Sigg, who’s being held on suspicion of first-degree murder and kidnapping in the death of Jessica Ridgeway.

Nazaryk notes the sketch and Sigg’s mug shot isn’t an exact match.

He also says that investigators are trying to determine if Sigg had access to a royal blue, four-door sedan described by witnesses in both cases.

The September child enticement cases involved a man who tried to lure two boys about the same age as Jessica into a car.

No suspects were identified in those incidents.
