(CBS/AP) DENVER - Police in the Colorado town where the body of missing 10-year-old Jessica Ridgeway was found want to question suspect Austin Sigg in two unsolved child enticement cases.
Police say Sigg, 17, confessed to them shortly before he was taken into custody on Tuesday night and told them where to find some of Jessica's remains in a crawl space under a home, CBS Denver reports.
Arvada police spokesman Sgt. Mark Nazaryk said Friday a sketch developed in the unsolved September incidents bears some resemblance to Sigg, who's being held on suspicion of first-degree murder and kidnapping in the Ridgeway case.
Nazaryk notes the sketch and Sigg's mug shot aren'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.
