KSAT 12 has learned the name of the San Antonio police sergeant under investigation for alleged DWI.

Sgt. Joe Meyers, a veteran of more than 20 years with SAPD allegedly wrecked his unmarked unit on Highway 281 North near Josephine on Thursday, Feb. 2.

Six of seven responding officers are now under investigation for alleged improprieties during an alleged cover-up of Meyer's crash.

Officers responded to a disturbance call at the intersection of North St. Mary's and East Mulberry last Thursday morning and found Meyers, who was off-duty, knocking on doors and windows of trucks thinking one of them was his.

Responding officers were soon joined by other officers who had responded to a related call for a crash on Highway 281 North near Josephine.

"If something did happen, we hope there's a thorough and swift investigation into what happened," said Daniel Garza, of the local chapter of Mothers Against Drunk Driving. "If there's something there and somebody needs to be held accountable, we hope that that happens."

Garza said he was grateful for San Antonio police Chief Bill McManus, who has been one of MADD's biggest supporters, for holding an impromptu press conference Monday afternoon to address the investigation, which had not gone public until then.

"I think that's a good move on his part, being proactive, and letting the community know, 'Hey, we have some possible infractions, something may have happened and we're going to look into it, we're going to take care of it.' And if there was a cover-up, not continue to cover it up," said Garza.

A lieutenant, three sergeants and two officers are under investigation for allegedly attempting to take the sergeant home as well as removing potential evidence from his vehicle.

Those six are on administrative duty while the investigation continues. The sergeant who crashed is on administrative leave.

McManus said Monday Meyers did give a blood sample later Thursday morning but those results have not been made public.

San Antonio Police Officers Associaton president Mike Helle said the six on-duty officers being investigated feel "like they've been gut-kicked."

Helle believes all six will be exonerated once the investigation is completed.
