Alyssa Bustamante and the Murder of Elizabeth Olten

Distressingly, there have been other teenage girl murderers, and if Alyssa Bustamante is convicted, she will join the ranks of other infamous female murderesses.

Diana Zamora killed a romantic arch-nemesis, Adrienne Jones in 1995, at the age of 17.

In Australia in 2006, the 16-year-old "Collie Killers," tried murder just for fun, strangling and suffocating their victim.

Mary Bell

One of the earliest known teenage female killers, wasn't even a teenager. Mary Bell strangled a three-year old boy and a four-year old boy just for kicks in 1968 at the tender age of 11.

In 1979, Brenda Spencer, 16, bored of Mondays at school, loaded the semiautomatic rifle her father had given her and blazed away, killing two adults and injuring eight children and a cop.

Still, a female offender as young as Bustamante is rare enough that, had it been ruled that she would be tried as a minor, authorities wouldn't have had the right facilities to handle a convicted violent female underage criminal. She would have likely been put in solitary confinement.
