ROSEBURG, Ore. -- Dustin Wallace, 18, who was found guilty of sexually abusing and killing 5-year-old Sahara Dwight in 2010, was in court Wednesday for the first day of his sentencing hearing.

Wallace walked into the court room making no eye contact with anyone and not showing any expression on his face.

Wallace waived his right to a jury trial, allowing the sentencing to be decided by Judge Randolph Garrison. The real battle between the defense and the prosecution is whether Wallace will face life in prison with, or without parole.

The defense called Wallace's mother Lisa to testify first. The questioning centered on Wallace's mental health.

She and Dustin were all tears, as she described his inability to socialize with others since he was 5-years-old. five years old. "Dustin had difficulty socially with other children beginning since kindergarten," she said. "Dustin had been in counseling and in to doctors his whole life."

Lisa also answered questions pertaining to an adult male by the name of Kevin, who was in his early 20's at the time. Kevin befriended Dustin when he was 15, and Dustin would watch pornographic websites with this male, according to his mother.

Lisa says she sent Dustin to a facility where they teach kids respect and how to psychologically deal with behavior and social skills.

His mother says Dustin was diagnosed with ADD, ADD aggressive, asbergers and depression.

During testimony, some incidents involving Dustin were discussed, such as him allegedly putting his sister's dog into a pillow case and swinging it around.Also discussed was an incident where he climbed into the shower with his sister when she was 13-years-old.

There was also an incident where Dustin allegedly cut the panties off of a girl who was staying the night.

Dr. Jerry Larsen, a psychiatrist and co-writer of the Diagnostic and Statistical Manual of Mental Health, also testified at the hearing Wednesday.

Dr. Larsen testified that if Wallace had been on his medication at the time of the incident, Wallace most likely would have not committed the crime. "Had he been on his meds, he would have been asleep and this would not have happened," the doctor said.

Larsen has seen and evaluated Wallace five times, and says Wallace has peer relationship problems, ADD, Asbergers and lack of development of social interaction.

At the time Wallace was in the academy before coming to Oregon to visit his father, he was taking Trazodone (an anti depressant) combined with Abilify (an anti-psychotic, which stabilizes his mood). When combined, the two meds helped him sleep, lift depression, and take away sexual urges.

When Wallace was sent to stay with his father for the summer in Oregon, he had been doing better for three months in the academy, and on new meds. He didn't take his meds to Oregon, and Dr. Larsen says you must be weaned off of those meds slowly. Going cold turkey can create major mood swings.

The hearing will resume Thursday at the Douglas County Courthouse.
