Williams worked for the 911 call center for a year and a half, the Houston Chronicle reported.
The calls she received ranged from robberies to homicides in addition to speeding cars, KHOU reported. Williams allegedly told investigators that she hung up on calls because she didn't want to talk to anyone.
Williams has been sentenced to 10 days in jail and 18 months probation, the Chronicle reported.
Her supervisor had been placed on a year of internal probation, officials said last year, the Chronicle reported.
