At this point, Barbara reportedly pistol-whipped Monohan, cracking her skull. The robbery attempt was a futile effort; the gang found nothing of value in the house and left empty-handed.
They later learned that they had missed about ,000 in jewels and valuables stashed in a purse in the closet near where they had murdered Monohan.
In March 1953, Barbara joined Perkins and Santo, as well as John True and Baxter Shorter (two of their associates), in robbing Monohan's home in Burbank.
Barbara reportedly gained entry by asking to use her phone.
Nicknamed "Bloody Babs" by the press, Graham was the third woman in California to be executed by gas.
She was arrested on vice charges in these naval cities and in San Pedro.
As a teenager, she was arrested for vagrancy and sentenced to serve time at Ventura State School for Girls, the same reform school where her mother had been.
Released from reform school in 1939, Barbara tried to make a new start for herself.
Once Monohan opened the door for Graham, the three men burst in.
The gang demanded money and the jewels from Monohan, but she refused to give them anything.
