A lieutenant with Pinal County Sheriff's Office was reprimanded earlier this year for repeatedly driving too fast.
An internal investigative report obtained by CBS 5 News revealed Lt. Tamatha Villar was stopped three times, driving about 90 mph or faster in a county vehicle between mid-2010 and March 2011.
Each time, Villar was stopped by a DPS officer. The incidents were either on the Interstate 10 or a frontage road. However, she was not ticketed during any of those traffic stops.
"The agency has the expectation that a ticket should have been written," said Bart Graves, spokesperson for DPS.
When asked if Villar received special treatment, Graves said, "No."
PCSO confirmed she was on duty when she was pulled over.
Records show the reasons she gave DPS for speeding included being late for a meeting, running late to pick up a child and "inattention."
It wasn't until the third incident, where investigators said she was exceeding 90 mph with her 10-year-old son in the car, that she was issued a written warning and a DPS captain alerted a PCSO chief.
Graves said anytime an officer pulls someone over, he or she has the discretion to write a ticket, issue a written warning or give a verbal warning.
"The discretion factor is something to keep in mind here, and in all three cases, these officers were put in difficult position because these are other law enforcement people that they come into contact with periodically in that district in central Arizona," said Graves.
Villar once served as public information officer for Sheriff Paul Babeu. Currently, she serves as Community Services lieutenant and oversees the PCSO Explorers program.
Villar declined to comment, saying she could not do so without prior approval from the sheriff's office.
