110 mph.

That's how fast police clocked Corner's car on Highway 40 (Interstate 64) just west of I-270.

Police stopped him, and his blood-alcohol level tested at 0.167 percent — more than twice the legal limit — for his third DWI.

The 2005 arrest came two months after his second DWI guilty plea, and it qualified him for a felony charge.

Prosecutors did charge him with a felony, but it was 18 months later.

After five more DWI arrests.

It's still unclear why it took so long.

Police quickly submitted the ticket, and prosecutors charged him with a misdemeanor as a temporary measure while they gathered his prior DWI records.

Then the months passed. Along the way, Corner kept skipping court, so prosecutors concede the case may have moved to the back burner.

Ten months after the 110-mph stop, he was arrested for allegedly driving drunk at nearly the same spot — although this time at only 80 mph. That was arrest No. 4.

Four months later came DWI arrest No. 5; four months after that, No. 6. The arresting officers — from Ballwin and Maryland Heights — eventually asked county prosecutors to file felony charges.

The Maryland Heights municipal clerk said prosecutors rejected the case for a felony, so the city tried to go for a lower charge, but the case got lost in the shuffle.

Ballwin police said they were told in mid-January 2007 that their case would wait because Corner had "other cases pending." Over the next month, Corner was arrested twice more for DWI, in St. George and Ballwin.

In his most recent DWI — No. 8 — police said he swerved into oncoming traffic on Big Bend and nearly rammed a car head-on before an officer stopped him.

Six days later, in February 2007, court records show Corner faced his first felony DWI — for the 110 mph stop that happened in August 2005.

Prosecutors soon added two more felony charges, for arrests No. 5 and No. 8, and Corner pleaded guilty. He served 120 days in prison.

He did not respond to repeated requests for comment.
