DENVER (CBS4/AP) — Police in a Colorado town where the body of a missing 10-year-old girl was found said Friday that they want to question a teenage suspect in two unsolved child enticement cases.
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, Arvada police spokesman Sgt. Mark Nazaryk said.
The sketch and Sigg’s mug shot wasn’t an exact match, Nazaryk noted.
“You know, there are some similarities,” said Nazaryk.
He also said investigators were 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. The incidents happened just miles from where Jessica was missing and from where Sigg lives.
“At some point we would like to have a conversation with him but I’m not sure if that is feasible at this point. We’d like to, that doesn’t stop what we’re doing,” said Nazaryk.
No suspects were identified in those incidents.
Sigg is being held without bail on suspicion of murder and kidnapping in the death of Jessica, and attempted murder and attempted kidnapping in the case of runner at a neighborhood lake in May. Prosecutors were expected to formally charge him next week.
In arguing that Sigg be held without bail, prosecutors disclosed that Sigg confessed and that DNA evidence in the case was overwhelming.
Jessica disappeared three weeks ago after leaving her home in the Denver suburb to walk to school. She never arrived. Her remains were found on Oct. 10.
In the May attack, a 22-year-old woman told police a stranger grabbed her from behind and put a rag that smelled of chemicals over her mouth. Police haven’t disclosed if the rag had a chemical on it meant to subdue the woman.
In order for detectives in Arvada to speak to Sigg they will have to first put in an official request through the Westminster Police Department and the Jefferson County District Attorney’s Office.
