A Homestead, Fla., man is facing DUI and reckless driving charges after authorities said he was clocked driving 127 mph with three small children in his car Saturday night in the Florida Keys.

Robert Rioseco, 46, is facing three counts of DUI with someone under 18 in the car, three counts of cruelty toward a child, one count of reckless driving and refusing to submit to a DUI test, the Monroe County Sheriff's Office said.

Rioseco's maroon Mitsubishi was first spotted by a deputy driving 87 mph in a 55 mph zone near Mile Marker 7 of the Overseas Highway around 11 p.m., the MCSO said.

The car reached 127 mph as the deputy radioed ahead for deputies south of him to keep an eye out for it. The vehicle was finally stopped at the 5.5 Mile Marker on Stock Island, authorities said.

When Rioseco got out of the car, he seemed impaired, smelled of alcohol and his behavior was "extremely erratic," the MCSO said. He was calm at times and at other times became agitated.

Rioseco was arrested and taken to jail. Once he got there, he appeared to have trouble walking and loudly refused to participate in sobriety exercises, swearing at the officers, the MCSO said.

Rioseco was being held without bond Sunday and it was unknown whether he has an attorney. The children were turned over to their mother, the MCSO said.
