The collection of Facebook and MySpace photos reveals a multi-faceted teenage girl who appears troubled and typical at the same time — smiling, seemingly carefree in one photo, holding her hand as a gun to her head in the next.

In one photo (top left), thin red lines of, what appear to be, self-inflicted cuts, are seen on Bustamante's left wrist.

Bustamante listed "cutting" and "killing people" as her hobbies in her Youtube profile, according to the Associated Press. That post has since been taken down.

Olten, the 9-year-old neighbor of Bustamante went missing in Cole County, Mo., on Oct. 21, 2009 while she was walking home from a neighbor's house. Her body was found two days later after a massive search effort and Bustamante led police to a grave in the woods, authorities said.

An autopsy revealed that Bustamante allegedly strangled, cut the throat of and stabbed Elizabeth; killing her, say police.

Bustamante then buried Olten in a grave she had dug five days before the murder, according to investigators.

Bustamante has been charged with Olten's murder and will be tried as an adult, a judge ruled last week.

On Friday Nov. 20, a judge ordered Bustamante to Fulton State Hospital for up to 96 hours of psychological evaluation after her public defender, John King, said she was "demonstrating signs of severe depression and anxiety," was on suicide watch in jail and had tried to cut herself with her finger nails.

Earlier in the week, juvenile justice officials testified that Bustamante attempted to commit suicide in 2007 and had been receiving mental health treatment for depression and cutting herself.
