A former Fresno IRS employee who illegally sold prescription drugs on the side pleaded guilty Tuesday to contributing to the death of an IRS co-worker.

According to court records, Margarita Aispuro-Camacho was a clerk at the IRS in Fresno. In May 2020, she sold morphine pills that she had been prescribed to a co-worker.

The co-worker died the next day from an overdose of morphine from Aispuro-Camacho and other prescription drugs the co-worker obtained elsewhere.

Aispuro-Camacho had previously sold morphine and other prescription drugs to the co-worker at least five other times for a few thousand dollars, prosecutors said.
