WESTMINSTER - Austin Reed Sigg, the Westminster 17-year-old arrested in the abduction and killing of 10-year-old Jessica Ridgeway, is described as a shy, loner who's won awards in student crime scene investigation competitions.
"He was very quiet, shy and to himself. I would say he was Gothic," said Brooke Olds, who has known Sigg for about nine years. "He never really talked about his family or his friends. Like, all he talked about was playing or spending time with us. He always wanted, just, to play capture the flag."
Sigg lives on 102nd Avenue, about a mile from Chelsea Park. That's where Jessica Ridgeway was walking to on Oct . 5 when she disappeared. Sigg lives on the opposite side of the park from the Ridgeway family.
On his arrest report, Sigg listed his occupation as a student at Arapahoe Community College.
Officers said Sigg was cooperative during the arrest and waived his right to an attorney and to remain silent, which allows a suspect to avoid saying something self-incriminating that can be used against him in court. Sigg is expected to make his first appearance in court on Thursday at 8 a.m.
Fascination With CSI
The CALL 7 Investigators have learned that Sigg had an interest in crime scene investigations -- or CSI. In high school, Sigg was part of HOSA, Health Occupation Students of America. He took second place with a team competing in a CSI event in the group's 2012 competition. He was also a finalist in forensic science at that same competition.
Sigg competed as a student from Warren Tech, described as "the premier Career and Technical Education center" for Jefferson County Public Schools on the district's website.
Warren Tech, which has campuses in Arvada and Lakewood, offers specialized programs, including Criminal Justice and Forensic Science.
Sigg's Internet Alter Ego -- Dohastvath
A 17-year-old Austin Sigg has a Myspace page that uses the profile name "Dohastvath." A video-gamer websites states that Dohastvath is "Austin."
Dohastvath has a YouTube account called "DNA." Both the YouTube and Myspace accounts use the same profile avatar -- a graphic image of a red-headed man in a long black coat and black pants.
On his YouTube profile, Dohastvath comments on a song called "Stalking Your Mom," which is performed by Wax. He also has a video link to the execution of hanging of former Iraq dictator Saddam Hussein.
Arrested At Westminster Home
Sigg was arrested at his family's home in Westminster at 7:45 p.m. on Tuesday 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.
The woman said she was jogging on a trail when a man grabbed her from behind and tried to put a chemical-laced rag over her mouth, police said. The woman escaped and called 911, police said.
Sigg's family home is less than a half mile from Ketner Lake.
Held At Youth Detention Center
Sigg is being held at the Mount View Youth Services Center, a state detention facility for youth offenders in Lakewood.
Mount View Youth Services Center is described as a "secure, co-ed multi-purpose institution" operated by the Colorado Department of Human Services' Division of Youth Corrections," according to the state Human Services website.
