Anna Ayala said she agreed to go along "out of stupidity and greed." She told a California probation officer she got cold feet before she planted the fingertip in her nearly finished bowl of chili March 22, 2005, the San Jose Mercury News reported.
Ayala and Jaime Plascencia both implicated Brian Rossiter in the crime. Plascencia paid Rossiter $100 for a fingertip severed in the tailgate of a truck at the Las Vegas asphalt plant where they worked.
Rossiter denied the fingertip was his until a DNA test and the Santa Clara (Calif.) County District Attorney said he could face prosecution if evidence warrants, the report said.
Ayala was sentenced to nine years and Plascencia 12 years, four months.
