Golden, Colorado- In a hearing that was open to the public only after media outlets got the Colorado Supreme Court to overturn a Judge’s decision to seal it, new facts surrounding the brutal murder of Jessica Ridgeway surfaced at the preliminary hearing of accused murderer Austin Sigg.  Cameras are not permitted in the courtroom.

Among the now confirmed revelations, a neighbor suspected Sigg in the early days following her disappearance and called the FBI directly.   The October 19th tip was allegedly due to Sigg’s very public obsession with death.  It has not been revealed how Sigg and his Mother were approached about providing a DNA sample that has been matched to clothing belonging to Jessica Ridgeway.

Four days after the FBI visited Sigg in the presence of his Mother and took a DNA sample for processing; Austin Sigg sat his Mother Mindy Sigg down, and proceeded to confess to the kidnapping and murder of Jessica Ridgeway in lurid detail.

…” I am a monster.”  -Austin Sigg

Sigg began the confession by telling his Mother he was a monster, and that after kidnapping Jessica and driving around with her for a while he brought her to the family residence while his Mother was at work and his brother was at school.    The teen who hoped to study mortuary science had dismembered Jessica Ridgeway and threw a garbage bag filled with her torso at Pattridge Park while keeping several other portions of the child’s remains under a crawlspace at the residence.   Sources inside the investigation speaking to BOC on the condition of anonymity have confirmed that not all of Jessica Ridgeway has been recovered to date.  A receipt for the garbage bags was located among the debris found at the park.  Sigg told Police he choked Ridgeway to death.  Her cause of death was asphyxiation.

Mindy Sigg called 911 on October 24th to alert Police that her son confessed.  During that call, Austin Sigg admitted to Jessica’s death at his hands, and also the attack on a female jogger at Kentner Lake.

The operator heard Austin in the background and asked to speak to him directly.

“I don’t exactly get why you’re asking me these questions. I murdered Jessica Ridgeway. I have proof that I did it,” Austin Sigg said. “You have to send a squad car down here, and I’ll answer any questions you want to ask me.”

Sigg attempted to use a homemade concoction of chloroform on a towel to overpower the woman over Memorial Day weekend and then attended a family vacation outside of the US a week later.

Sigg is facing additional charges in the Ridgeway case as child pornography was located on his computer, but the attempted murder and attempted sexual assault charges have been dropped in the Kentnor jogger case due to insufficient evidence.

When Westminster Police arrived at the Sigg residence to interview Sigg, the first thing he said to them was that he did not rape or torture the fifth grader.  No seminal fluid has been recovered in this case.

Sigg was ordered held without bail until his arraignment March 12, 2013.  Sigg is facing trial as an Adult although he was 17 at the time of both incidents.  Under Colorado law, Sigg will not be eligible for the death penalty or life in prison without the possibility of parole as he was a minor at the time of the crimes.
