Prosecutors say a Colorado teenager has confessed in the abduction and killing of a 10-year-old girl and in a separate attack on a runner.
Authorities also said Thursday they have "overwhelming" DNA evidence against 17-year-old Austin Reed Sigg.
The Jefferson County District Attorney announced on Thursday morning that he will try the suspect arrested in the abduction and murder of Jessica Ridgeway as an adult.
7NEWS in Denver reports that Austin Sigg, 17, made his first court appearance on Thursday. He appeared in a bright, light green jumpsuit. His hands and feet were both shackled.
Sigg's mother was in court. Jessica Ridgeway's mom, aunt and other family members took up an entire row in the courtroom. All were dressed in purple, Jessica's favorite color. Jessica's mother was wearing a purple ribbon in her hair.
7NEWS reporter Russell Haythorn said Sigg appeared calm through the proceedings. At one point he interrupted the judge because he said he didn't understand a portion of the advisement hearing.
The judge paused the proceedings while Sigg's attorney's gave him an explanation.
The charges were not read in court on Thursday, but the judge did tell Sigg he was being held in two separate cases. Another hearing was scheduled for next Tuesday.
The defense asked the judge to put all documents in the case under seal and issue a gag order in the case. The judge agreed to seal the documents, but did not issue a gag order.
In court, Sigg revoked the waiver of his rights.
The judge ordered Sigg be held without bond.
Sigg is being held on suspicion of two counts of murder in the first degree, one count of second degree kidnapping and two counts of criminal attempt.
The first three charges (murder and kidnapping) are related to the Jessica Ridgeway case, according to Westminster Police spokesman Trevor Materasso.
Materasso said the last two charges, attempted murder and attempted kidnapping are related to a May incident where a male attacked a 22-year-old woman jogging around Ketner Lake in Westminster.
Rob Sigg, the father of Austin Sigg, issued this statement today:
"First, I would ask for your prayers and support for the Ridgeway family. There are no words to express the sorrow that I and my family feel for their pain they are suffering. We are devastated by the knowledge that my son, Austin Sigg, has been arrested and will be charged with the murder of their beautiful daughter Jessica. This
horrible event is a tragedy for both the families, as well as the community. I ask also for your prayers and support for Austin's mother, whose courageous act … unimaginably painful for any parent … has put this tragedy on the path to resolution. I am hopeful that as the legal process unfolds, the Ridgeway family may come to know peace."
