A routine speed enforcement operation in Nocatee turned into something much bigger Sunday evening, when St. Johns County sheriff's deputies pulled over 49-year-old Cipriano Mendoza-Alcon and discovered he was wanted on multiple felony warrants, including sexual battery on a minor. Deputies also determined he did not have a valid driver's license and was in the country illegally, leading to his arrest on the spot.

According to News4Jax, deputies made the arrest during what the outlet described as a routine speed enforcement operation in Nocatee. The stop, which the St. Johns County Sheriff's Office says happened Sunday evening, quickly escalated once deputies ran Mendoza-Alcon's information and found he did not have a driver's license, resulting in an additional charge for driving without one.

That check also turned up multiple active felony warrants out of Brevard County, per the same account, tied to sexual battery on a minor between the ages of 12 and 18, false imprisonment and kidnapping. As Action News Jax reported, Mendoza-Alcon was taken into custody in Nocatee and is now being held at the St. Johns County Jail without bond.

Federal Detainer Added to the Case

Deputies said they determined that Mendoza-Alcon was in the United States illegally, the report notes, and U.S. Immigration and Customs Enforcement placed a detainer on him following the arrest. The specifics of when or how that determination was made were not detailed in the sheriff's office account.

Federal guidance on detainers, per an ICE policy document, says that, absent extraordinary circumstances, officers should issue a detainer when there is reason to believe an individual is subject to removal and at least one additional listed condition applies, such as felony charges or convictions, specified misdemeanor histories, a removal order, or certain public-safety or security risks.

Sheriff Points to Cooperation With Federal Partners

St. Johns County Sheriff Rob Hardwick said the traffic stop resulted in the apprehension of a dangerous subject from the community, the same report states. He added that crimes against children are never tolerated, framing the arrest as evidence of the value of working alongside immigration authorities.

“Collaborating with our federal partners in Immigration to ensure violent offenders are held accountable for their actions and removed accordingly,” Hardwick said, according to the outlet's report. The sheriff's comments tied the outcome of an otherwise ordinary speed enforcement detail to the broader warrants that had been outstanding against Mendoza-Alcon out of Brevard County.

Mendoza-Alcon remains held without bond at the St. Johns County Jail as the case moves forward. No additional court records or booking documents were made available beyond the sheriff's office's account of the arrest.
