Mo. teen killer had troubled family, depression

JEFFERSON CITY, Mo. — Abandoned by her mother and missing a father in prison, Alyssa Bustamante had plunged to the depths of depression before, once overdosing on a large bottle of painkillers, slicing her skin hundreds of times and carving the word "hate" in her arm. She recovered from her suicide attempt and was prescribed an antidepressant drug.

Two years later, an increased dosage of the antidepressant Prozac might have made her more prone to do the unthinkable: strangling, slicing the throat and repeatedly stabbing a 9-year-old neighbor girl to death, Bustamante's defense attorneys suggested Monday during a sentencing hearing.

Defense attorneys were to continue presenting evidence Tuesday as they sought to persuade a judge to give Bustamante something less than the maximum of life in prison with the possibility of parole for the October 2009 slaying of Elizabeth Olten in a small town just west of Jefferson City. Bustamante, who recently turned 18, pleaded guilty last month to second-degree murder and armed criminal action. She was 15 at the time of the crimes and is being sentenced as an adult.

Although Bustamante has remained largely silent in court, prosecutors are using her written words against her to urge a long prison sentence. In a journal entry on the night of the killing, Bustamante described the slaying of Elizabeth with a sense of exhilaration and a typical teenage reliance on texting-style acronyms.

"I strangled them and slit their throat and stabbed them now they're dead," Bustamante wrote in her journal, which was read in court by a handwriting expert. "I don't know how to feel atm. It was ahmazing. As soon as you get over the 'ohmygawd I can't do this' feeling, it's pretty enjoyable. I'm kinda nervous and shaky though right now. Kay, I gotta go to church now...lol."

Bustamante headed off to a youth dance at her church while a massive search began for the missing girl. Bustamante's grandmother and legal guardian, Karen Brooke, was asked in court if she noticed anything different about Bustamante as they left the home that evening. She appeared a bit happier than usual, Brooke said.

Brooke said her own daughter — Bustamante's mother — had lived a wild life of drug and alcohol abuse and had abandoned her children several times, including once not long before Bustamante attempted suicide on Labor Day 2007 by swallowing a large bottle of Tylenol and making hundreds of cuts on her arms — even carving the word "hate" in one of them.

After the suicide attempt, Bustamante was prescribed the antidepressant drug Prozac. Just two weeks before killing Elizabeth, Bustamante started taking a higher dosage, which a defense psychiatrist testified could have increased her mood swings and tendency toward violence.
