Oxford woman arrested at Lafayette County checkpoint on fourth DUI charge

A Lafayette County checkpoint on County Road 101 led deputies to an Oxford woman now facing a fourth DUI charge or greater, along with disorderly conduct and resisting arrest, after officers said they saw signs of intoxication during a driver’s license safety stop.

Deputies identified the driver as 43-year-old Tish Sisk of Oxford, who was behind the wheel of a Black Nissan Pathfinder. According to the arrest report, the checkpoint contact turned into a DUI investigation after deputies observed obvious signs of intoxication. The report says Sisk actively resisted before deputies placed her under arrest and took her to the Lafayette County Detention Center.

A criminal history check showed several prior DUI arrests in Mississippi, raising the case beyond a routine impaired-driving stop and into the category of repeat-offender enforcement. In Mississippi, a fourth DUI conviction is treated as a felony regardless of how much time has passed between the earlier violations. State driving officials also say a fourth conviction can trigger a full sentence-length suspension of a Class R license, and courts may consider an ignition-interlock-restricted license in some cases.

The checkpoint itself underscores why local deputies continue to use roadside enforcement on county roads that carry more than commuter traffic. Roads such as County Road 101 connect neighborhoods, schools, farms and county infrastructure, making impaired driving a broader public-safety issue than a simple traffic stop might suggest. Mississippi law sets the adult DUI threshold at 0.08% blood alcohol concentration, and the arrest shows how quickly a checkpoint can move from administrative license checks to an alcohol-related investigation when officers spot warning signs.

A Lafayette County justice court judge set Sisk’s bond at $15,000 as the case moves through the county system. The Lafayette County Sheriff’s Department, led by Sheriff Joey East, handles countywide law enforcement and jail administration from 711 Jackson Ave. East in Oxford, and its booking line is 662-234-6421. Mississippi Department of Public Safety arrest data are compiled from the Mississippi Criminal History System, the statewide recordkeeping network that tracks arrests reported by state, county and municipal agencies.
