A former 911 operator in Houston has been found guilty of hanging up on emergency calls. Crenshanda Williams, 44, was sentenced to 10 days in jail and 18 months of probation for interfering with emergency telephone calls. Calls she terminated included reports of robberies, speeding vehicles, and murders. Records showed that thousands of calls shorter than 20 seconds were attributed to her hanging up. She said she hung up because at those times she did not want to talk to anyone.
