What would you do if your child confessed to a murder? Would you turn him in? Would you support him through the court process by hiring a lawyer etc. or just tell him to plead guilty and be done with it? Would it make any difference if he could get the death penalty?
Sigg was arrested after confessing to his mother, who then called police in Colorado so her son could turn himself in, sources said.
Investigators scoured the Westminster, Colo., home overnight where Sigg lives with his mother. FBI agents combed the backyard for clues and towed away his car.
"He was always egotistical, but I never thought he would go this far," Austin Cassie, who has known Sigg since elementary school, said. "I mean, he wasn't ever that violent of a person. He was more bark than bite."
Sigg is a student at Arapahoe Community College Littleton, Colo., according to his arrest report, where classmates said he was studying mortuary science. He took second place in a high school competition involving crime-scene investigations.
